Description

Data processing method and related equipment
Technical Field
The application relates to the field of artificial intelligence, in particular to a data processing method and related equipment.
Background
Artificial intelligence (Artificial Intelligence, AI) is the theory, method, technique and application system that uses a digital computer or a machine controlled by a digital computer to simulate, extend and extend human intelligence, sense the environment, acquire knowledge and use the knowledge to obtain optimal results. In other words, artificial intelligence is a branch of computer science that attempts to understand the essence of intelligence and to produce a new intelligent machine that can react in a similar manner to human intelligence. Artificial intelligence, i.e. research on design principles and implementation methods of various intelligent machines, enables the machines to have functions of sensing, reasoning and decision.
In order to ensure the performance of the neural network when the neural network performs the target task, the number of the existing application model parameters based on the deep neural network often reaches 10-100M, and for some terminal devices (such as intelligent wearable devices or intelligent sensors) with relatively tight computing resource limitation, the computing resources of the terminal devices are often difficult to complete the computation of the whole neural network.
At present, data to be processed of a user can be acquired at a terminal device side, the data to be processed is sent to a server, and after the data to be processed is processed by the server through a neural network, a prediction result corresponding to the data to be processed is obtained and returned to the terminal device.
However, since the data to be processed of the user needs to be transmitted in the network, and the server can obtain the original data to be processed, the privacy protection degree of the user data is weaker.
Disclosure of Invention
The embodiment of the application provides a data processing method and related equipment, and because the operation of a second neural network is completed by a server, the computer resources of terminal equipment occupied in the calculation process of the whole neural network can be reduced; the terminal equipment inputs the data to be processed into the first neural network for calculation and then sends the first intermediate result to the server, so that the leakage of the original data to be processed is avoided, and the protection degree of the privacy of the user data is improved; and the calculation of the third neural network in the whole neural network is also executed by the terminal equipment side, which is beneficial to further improving the protection degree of the privacy of the user data.
In order to solve the technical problems, the embodiment of the application provides the following technical scheme:
in a first aspect, an embodiment of the present application provides a data processing method, which may be used in the field of artificial intelligence. The method is applied to a data processing system, the data processing system comprises a first terminal device and a server, a first neural network and a third neural network are deployed on the first terminal device, a second neural network is deployed on the server, the first neural network, the second neural network and the third neural network form a target neural network, the first neural network is located before the second neural network, the third neural network is located behind the second neural network, and the second neural network is located between the first neural network and the third neural network.
Further, the "the first neural network is located before the second neural network" means that in the process of inputting the data to be processed into the target neural network and performing data processing through the target neural network, the data to be processed will first pass through the first neural network in the target neural network, and then pass through the second neural network in the target neural network. The concept that the third neural network is located after the second neural network can also be understood by the foregoing description, and will not be repeated here.
The data processing method comprises the following steps: the method comprises the steps that first terminal equipment inputs data to be processed into a first neural network, a first intermediate result generated by the first neural network is obtained, and the first intermediate result is sent to a server; the first intermediate result generated by the first neural network may also be referred to as a first hidden vector generated by the first neural network, where the first intermediate result generated by the first neural network includes data required by the second neural network when performing data processing; further, the "first intermediate result generated by the first neural network" includes data generated by the last neural network layer in the first neural network, or the "first intermediate result generated by the first neural network" includes data generated by the last neural network layer in the first neural network and data generated by other neural network layers in the first neural network. The server inputs the first intermediate result into a second neural network to obtain a second intermediate result generated by the second neural network, and sends the second intermediate result to the first terminal equipment; the meaning of "second intermediate result" may be understood with reference to the meaning of "first intermediate result", and will not be described herein. The first terminal device inputs the second intermediate result into a third neural network to obtain a prediction result which is generated by the third neural network and corresponds to the data to be processed, and the type of information indicated by the prediction result corresponds to the type of the target task.
The neural network deployed on the first terminal device has the following changes at two different moments, namely a first moment and a second moment: the number of neural network layers in the first neural network changes or the number of neural network layers in the third neural network changes.
In the implementation manner, since the operation of the second neural network is completed by the server, the computer resources of the first terminal equipment occupied in the calculation process of the whole target neural network can be reduced; the first terminal equipment sends the first intermediate result to the server after the first neural network calculates the data to be processed before the data to be processed is input, so that the leakage of the original data to be processed is avoided, and the protection degree of the privacy of the user data is improved; and the calculation of the rear third neural network in the whole target neural network is also executed by the first terminal equipment side, so that the protection degree of the privacy of the user data is further improved. Because an attacker may reversely push the intermediate result sent between the first terminal device and the server according to the obtained intermediate result to obtain the original data to be processed, and for the two different moments of the first moment and the second moment, the number of the neural network layers deployed on the first terminal device is changed, that is, different intermediate results are sent between the first terminal device and the server at different moments, so that the difficulty of the attacker in obtaining the original data to be processed is further increased, and the protection degree of privacy of the user data is further improved.
In one possible implementation manner of the first aspect, at a first moment, the first neural network includes N neural network layers, the third neural network includes S neural network layers, at a second moment, the first neural network includes N neural network layers, the third neural network includes S neural network layers, where N and N are different and/or S and S are different, the method further includes: the server sends n neural network layers and s neural network layers to the first terminal device.
In the implementation manner, when the number of the neural network layers deployed on the first terminal device changes, the server can send the updated first neural network and the updated third neural network to the first terminal device, so that the difficulty of an attacker in determining the neural network deployed on the first terminal device is further improved, the difficulty of the attacker in reversely pushing the intermediate result to obtain the original data to be processed is further improved, and the privacy protection degree of the user data is further improved.
In one possible implementation manner of the first aspect, the method further includes: the server determines a first neural network and a third neural network from target neural networks, wherein the target neural networks are the neural networks for executing target tasks, and the determining factors of the first neural network and the third neural network comprise: and when the target task is not executed, the occupied amount of the processor resource of the first terminal device and/or the occupied amount of the memory resource of the first terminal device. Optionally, the determining factors of the first neural network and the third neural network may further include any one or more of the following: the number of processes currently running on the first terminal device, the time each process on the first terminal device has been running, the running state of each process on the first terminal device, or other enabling factors, etc., are not exhaustive herein. Further, the evaluation index of the "occupation amount of the memory resource of the first terminal device" may include any one or more of the following indexes: the size of the total memory resource of the first terminal device, the size of the occupied memory resource of the first terminal device, the occupancy rate of the memory resource of the first terminal device or other evaluation indexes, etc. The evaluation index of the "occupation amount of the processor resource of the first terminal device" may include any one or more of the following: the occupation rate of the processor resources of the first terminal device, the occupation duration of each processor on the first terminal device for executing the target task, the load of the processor on the first terminal device for executing the target task allocation, the performance of the processor on the first terminal device for executing the target task allocation, or other evaluation indexes capable of reflecting the occupation amount of the processor resources on the first terminal device for executing the target task, etc. are not exhaustive herein.
In this implementation manner, since a plurality of application programs are usually required to be run on the first terminal device, computer resources that can be allocated to the target task by the first terminal device may be different at different times of the same terminal device, and determining factors of the first neural network and the third neural network include an occupation amount of a processor resource of the first terminal device and/or an occupation amount of a memory resource of the first terminal device, which is beneficial to ensuring that the neural network deployed on the first terminal device can be matched with an computing power of the first terminal device, so as to avoid increasing an computing pressure of the first terminal device in a process of executing the target task.
In a possible implementation manner of the first aspect, the system for data processing further includes a second terminal device, the number of the neural network layers in the first neural network deployed on the first terminal device and the first neural network deployed on the second terminal device are different, and/or the number of the neural network layers in the third neural network deployed on the first terminal device and the third neural network deployed on the second terminal device are different; the first terminal device and the second terminal device are different types of terminal devices, and/or the first terminal device and the second terminal device are different types of terminal devices in the same type.
In this implementation manner, since the configuration of the computer resources of the different types of terminal devices may be different, the configuration of the computer resources of the different types of terminal devices in the same type may also be different, and thus the different types of terminal devices or the computer resources that the different types of terminal devices in the same type can be allocated to the target task may also be different.
In one possible implementation manner of the first aspect, the first neural network and the second neural network may be obtained by splitting a target neural network for the server. The server may store a first mapping relationship, where the first mapping relationship may store the number of neural network layers deployed on each type of terminal device, and when the server needs to deploy the first neural network and the second neural network to a new first terminal device, two split nodes corresponding to the first terminal device of the target type may be determined according to the target type and the first mapping relationship of the new first terminal device. Or, the server may store a second mapping relationship, where the second mapping relationship may store the number of neural network layers corresponding to at least one model of each type of terminal device, and when the server needs to deploy the first neural network and the second neural network to a new first terminal device, two split nodes corresponding to the first terminal device of the target type may be determined according to the target type, the target model, and the second mapping relationship of the new first terminal device. Wherein the determining factors of the first neural network and the third neural network in the first mapping relation (or the second mapping relation) may include any one or a combination of multiple factors as follows: when the first terminal device performs the target task, a pre-estimate of the processor resources allocated by the first terminal device, a pre-estimate of the memory resources allocated by the first terminal device, or other types of factors, etc.
In one possible implementation manner of the first aspect, processor resources occupied during data processing by the first terminal device through the first neural network and the third neural network are smaller than processor resources occupied during data processing by the server through the second neural network, and memory resources occupied during data processing by the first terminal device through the first neural network and the third neural network are smaller than memory resources occupied during data processing by the server through the second neural network.
In the implementation manner, the second neural network is deployed on the server, and the second neural network occupies more processor resources and more memory resources in the process of data processing, so that the computer resources of the first terminal equipment occupied in the whole calculation process of the neural network can be further reduced, and the calculation pressure of the first terminal equipment in the process of executing the target task can be reduced; because most of calculation in the data processing process of the whole neural network is executed by the server, the deep neural network with more parameters can be adopted to generate the prediction result fixed with the data to be processed, and the accuracy of the prediction result generated by the whole neural network is improved.
In a possible implementation manner of the first aspect, the data to be processed may be specifically represented as any one of the following data: sound data, image data, fingerprint data, outline data of an ear, sequence data capable of reflecting habit of a user, text data, point cloud data, or other types of data, and the like. In the implementation mode, various expression forms of the data to be processed are provided, the application scene of the scheme is expanded, and the implementation flexibility of the scheme is improved.

And A3, the server inputs the first intermediate result into the second neural network to obtain a second intermediate result generated by the second neural network, and the second intermediate result is sent to the first terminal equipment. A4, the first terminal equipment inputs the second intermediate result into a third neural network to obtain a prediction result which is generated by the third neural network and corresponds to the data to be processed; it should be understood that the example in fig. 3 is merely for facilitating understanding of the present solution, and is not intended to limit the present solution. Specifically, referring to fig. 4, fig. 4 is a schematic flow chart of a data processing method according to an embodiment of the present application, where the data processing method according to the embodiment of the present application may include:
401. The method comprises the steps that a server sends a first neural network and a third neural network to a first terminal device, wherein a second neural network is deployed on the server, the first neural network comprises N neural network layers, the second neural network comprises M neural network layers, the third neural network comprises S neural network layers, and the first neural network, the second neural network and the third neural network form a target neural network.
In some embodiments of the present application, the server may determine the number of neural network layers in the first neural network and the number of third neural network layers corresponding to the first terminal device, where at the first moment, the first neural network includes N neural network layers, the second neural network includes M neural network layers, the third neural network includes S neural network layers, the first neural network, the second neural network, and the third neural network form a target neural network, and each of N, M and S is an integer greater than or equal to 1.
The server may send the first neural network and the third neural network to the first terminal device, the first terminal device receives and stores the first neural network and the third neural network, so as to deploy the first neural network and the third neural network on the first terminal device, and deploy the second neural network on the server.
It should be noted that, the server may further deploy the first neural network and the third neural network on the first terminal device in other manners, for example, deploy the first neural network and the third neural network on the first terminal device by using a removable storage device, which is not exhaustive in the embodiment of the present application.
In addition, the target neural network in the embodiment of the present application may be a neural network after performing pretreatment, where the pretreatment may be pruning, distillation or other processing manners for reducing the number of parameters of the standard neural network, which is not exhaustive herein. Alternatively, the target neural network in the embodiment of the present application may be a standard neural network, and the specific expression form of the target neural network may be determined in conjunction with an actual application scenario, which is not limited herein.
The server performing step 401 may be the server 240 in the data processing system shown in fig. 2a, or may be the first server 241 in the data processing system shown in fig. 2 b.
The target neural network is a neural network for performing a target task, which may be any type of task. As an example, the target task may be a function of authentication by recognizing input user data, and the authentication-like task may be voiceprint recognition, face recognition, fingerprint recognition, ear print recognition, or a task of authentication using other types of users. As another example, for example, the target task may be a personalized recommendation class task that may generate a charging scheme for personalization, a personalized recommendation recipe, a personalized recommendation exercise scheme, a personalized recommendation movie work, a personalized recommendation application, and so forth, although not exhaustive herein. As another example, the target task may be a task of a feature extraction class, which may be extraction of voiceprint features, extraction of image features, or extraction of text features, and so forth. As another example, the target task may also be a task of identifying voice content, translating text between different languages, identifying a target in a surrounding environment, migrating an image style, or executing by other first terminal devices using a neural network, and the like, which types of tasks the target task is embodied as is not exhaustive in the embodiment of the present application.
The target neural network may be embodied as a convolutional neural network, a cyclic neural network, a residual neural network, or other type of neural network, etc., and the specific morphology of the target neural network may be determined in conjunction with a "target task" being a task of a particular neural type, without limitation herein. The target neural network includes a plurality of neural network layers.
Optionally, the first neural network, the second neural network and the third neural network are split from the target neural network. In the embodiment corresponding to fig. 4, the multiple neural network layers included in the whole target neural network are split into three parts, that is, two split nodes corresponding to the target neural network in this embodiment are included, where the two split nodes include a first split node and a second split node, the first split node is a split node of the first neural network and the second neural network, and the second split node is a split node of the second neural network and the third neural network.
The term "the first neural network is located before the second neural network" means that in the process of inputting the data to be processed into the target neural network and performing data processing through the target neural network, the data to be processed will first pass through the first neural network of the target neural network and then pass through the second neural network of the target neural network. That is, the order of each neural network layer in the target neural network refers to the process that data is transmitted forward in the target neural network, the neural network layer through which the data passes first represents the neural network layer with the front position, and the neural network layer through which the data passes later represents the neural network layer with the rear position. The concept that the third neural network is located after the second neural network can also be understood by the foregoing description, and will not be repeated here.
In order to more intuitively understand the present solution, please refer to fig. 5, fig. 5 is a schematic diagram of two split nodes corresponding to a target neural network in the data processing method provided by the embodiment of the present application, in fig. 5, the target neural network is taken as a residual neural network (residual networks, reserve) 34, a target task is taken as an example of extracting voiceprint features, as shown in fig. 5, the target neural network includes 4 residual blocks (residual blocks), a neural network layer located before a first split node in the target neural network is referred to as a first neural network, a neural network layer located between the first split node and a second split node is referred to as a second neural network, a neural network layer located after the second split node is referred to as a third neural network, that is, the first neural network is located before the second neural network, and it should be understood that the example in fig. 5 is merely for facilitating understanding the present solution and is not limited to the present solution. Further, the parameter amounts of the respective parts in the neural network in fig. 5 are disclosed in the form of a table as follows.
Neural network Layer (Layer) Parameter number (Parameters)
First convolution layer 3*3*32=288
Residual block 1 (3*3*32*32*2)*3=55296
Residual block 2 (3*3*64*64*2)*4=294912
Residual block 3 (3*3*128*128*2)*6=1769472
Residual block 4 (3*3*256*256*2)*3=3538944
Pooling layer -
First linear connection layer 256*8*256=524288
Second linear connection layer 256*256=65536
TABLE 1
Referring to table 1 above, it can be seen that most of the parameter calculation in the data processing process of the entire target neural network is consumed in the calculation of the residual block 1 to the residual block 4, the parameter amounts of the first convolution layer and the last Linear connection (Linear) layer are small, and the analysis shows that the first plurality of neural network layers and the last plurality of neural network layers in the entire target neural network can be deployed in the first terminal device, and the middle plurality of neural network layers are deployed in the server, so that the computer resources on the first terminal device consumed in the data processing process of the entire target neural network can be greatly reduced.
In the embodiment of the application, the number of the neural network layers deployed by the target is determined for the first time aiming at the server. In one implementation, the number of neural network layers in the first neural network deployed on the first terminal device is different from the number of neural network layers in the first neural network deployed on the second terminal device, and/or the number of neural network layers in the third neural network deployed on the first terminal device is different from the number of neural network layers in the third neural network deployed on the second terminal device.
The first terminal device and the second terminal device may be different types of terminal devices. As an example, for example, the first terminal device is a wristwatch and the second terminal device is a mobile phone; as another example, for example, the first terminal device is a lamp and the second terminal device is an air conditioner; as another example, the first terminal device is a cell phone, the second terminal device is a tablet, etc., which is not exhaustive herein.
Or the first terminal device and the second terminal device are terminal devices with different models in the same type. It should be noted that, in this solution, when two different terminal devices (i.e., the first terminal device and the second terminal device) are configured with part of the neural network layers included in the target neural network, when the number of the neural network layers deployed on the first terminal device and the number of the neural network layers deployed on the second terminal device are different, the first terminal device and the second terminal device may be different types of terminal devices or different types of terminal devices in the same type, but do not represent that the number of the neural network layers deployed on any two different types of terminal devices is different, and also do not represent that the number of the neural network layers deployed on any two different types of terminal devices in the same category is different.
Optionally, if the first neural network, the second neural network, and the third neural network are obtained by splitting the target neural network, in the embodiment corresponding to fig. 4, the target neural network corresponds to two splitting nodes, where "the splitting nodes corresponding to the target neural network are different" means that the two splitting nodes corresponding to the first terminal device are not identical to the two splitting nodes corresponding to the second terminal device.
Specifically, in the embodiment corresponding to fig. 4, the following three cases exist in the case that the split node corresponding to the target neural network is different: in one case, the first split node corresponding to the first terminal device is the same as the first split node corresponding to the second terminal device, and the second split node corresponding to the first terminal device is different from the second split node corresponding to the second terminal device. In another case, the first split node corresponding to the first terminal device is different from the first split node corresponding to the second terminal device, and the second split node corresponding to the first terminal device is the same as the second split node corresponding to the second terminal device. In another case, the first split node corresponding to the first terminal device is different from the first split node corresponding to the second terminal device, and the second split node corresponding to the first terminal device is different from the second split node corresponding to the second terminal device.
Correspondingly, in the embodiment corresponding to fig. 4, the "split node corresponding to the target neural network is the same" means that the first split node corresponding to the first terminal device is the same as the first split node corresponding to the second terminal device, and the second split node corresponding to the first terminal device is the same as the second split node corresponding to the second terminal device.
In the embodiment of the application, as the configuration of the computer resources of the terminal devices of different types may be different, the configuration of the computer resources of the terminal devices of different types in the same type may also be different, so that the computer resources which can be allocated to the target task by the terminal devices of different types or the terminal devices of different types in the same type may also be different.
Specifically, a procedure of determining two split nodes corresponding to a certain first terminal device with respect to the server. If the number of the neural network layers deployed on the terminal devices of different types may be different, the number of the neural network layers deployed on the terminal devices of different types in the same type may be the same, a first mapping relationship may be preconfigured on the server, the number of the neural network layers deployed on each type of terminal device may be stored in the first mapping relationship, and when the server needs to deploy the first neural network and the second neural network on a new first terminal device, two split nodes corresponding to the first terminal device of the target type may be determined according to the target type and the first mapping relationship of the new first terminal device.
Before step 401 is performed, when a part of the neural network layers in the target neural network needs to be deployed on the first terminal device, a first request may be sent to the server, where the first request is used to request to acquire the part of the neural network layers in the target neural network, and the first request also carries the target type of the first terminal device. The server acquires two split nodes corresponding to the target type from the first mapping relation according to the received target type of the first terminal equipment; and splitting the first neural network and the third neural network from the target neural network by the server according to the acquired two splitting nodes.
The first mapping relationship may be stored on the server in a table, an array, or other forms. For a more intuitive understanding of the present solution, the first mapping relationship is shown in the form of a table below.
TABLE 2
As shown in table 2 above, when the first terminal device appears as a different type of terminal device, the two split nodes corresponding to the target neural network may be the same or different. For example, when the first terminal device appears as a lamp and the first terminal device appears as a refrigerator, the two split nodes corresponding to the target neural network are different; for another example, when the first terminal device is represented as a refrigerator and the first terminal device is represented as an air conditioner, the two split nodes corresponding to the target neural network are the same, and it should be understood that the example in table 2 is only for facilitating understanding of the content in the first mapping relationship, and is not limited to this scheme.
More specifically, in one implementation, the first mapping relationship is sent to the server by the other device. In another implementation, the first mapping is generated by a server.
Further, the determining factors of the first neural network and the third neural network in the first mapping relationship may include any one or a combination of the following factors: when the first terminal device performs the target task, a pre-estimate of the processor resources allocated by the first terminal device, a pre-estimate of the memory resources allocated by the first terminal device, or other types of factors, etc.
That is, before performing step 401, the server may determine the number of neural network layers deployed on each type of terminal device according to the above-mentioned index of each type of terminal device, according to the above-mentioned index of each type of terminal device. The more the pre-estimated amount of the processor resources allocated by the first terminal device is, the more the number of the neural network layers allocated on the first terminal device is, and the less the pre-estimated amount of the processor resources allocated by the first terminal device is, the fewer the number of the neural network layers allocated on the first terminal device is. The more the pre-estimated amount of memory resources allocated by the first terminal device is, the more the number of neural network layers allocated on the first terminal device is, and the fewer the pre-estimated amount of memory resources allocated by the first terminal device is, the fewer the number of neural network layers allocated on the first terminal device is.
The processor may specifically be represented by a central processing unit (central processing unit, CPU), a graphics processor (graphics processing unit, GPU), an application specific integrated circuit (application specific integrated circuit, ASIC), or other type of processor, etc., where the specific type of processor configured on the first terminal device may be determined in conjunction with the actual product form, and is not limited herein.
If only one processor is allocated on the first terminal device to perform the target task, the evaluation index of "the pre-estimate of the processor resource allocated by the first terminal device" may include any one or more of the following elements: the occupation time of the processor allocated by the first terminal device for executing the target task and the performance of the processor allocated by the first terminal device for executing the target task. If at least two processors are allocated on the first terminal device to perform the target task, the evaluation index of "the pre-estimate of the processor resource allocated by the first terminal device" may include any one or more of the following elements: the occupation duration of each processor allocated by the first terminal device to execute the target task, the performance of each processor allocated by the first terminal device to execute the target task, the number of processors, the type of each processor or other elements, and the like.
Further, the evaluation index of the performance of the processor may be any one or more of the following evaluation indexes: floating-point operations (flow) performed by the processor per second, the number of millions of instructions (dhrystone million instructions executed per second, DMIPS) performed by the processor per second, i.e., a measure of how many millions of instructions are performed by the processor per second or other indicators for evaluating the performance of the processor, or other types of performance evaluation indicators for the processor may be employed, etc., without being exhaustive.
The evaluation index of the "pre-estimated amount of memory resources allocated by the first terminal device" may be the size of the memory space of the memory allocated by the first terminal device for executing the target task.
It should be noted that, the "occupation duration of the processor allocated by the first terminal device to execute the target task" and the "size of the memory space of the memory allocated by the first terminal device to execute the target task" may be a predicted value range or a predicted determined value. Further, the unit of "the occupied period of the processor allocated by the first terminal device to execute the target task" may be millions of instructions (million instructions executed per second, MIPS), seconds or other types of time units executed per second, etc., which are not exhaustive herein.
As an example, for example, the occupation duration of the processor allocated by the first terminal device to perform the target task may be 0.5MIPS-1MIPS, and the size of the memory allocated by the first terminal device to perform the target task may be 20M-30M; as another example, for example, the occupation duration of the processor allocated by the first terminal device to perform the target task may be 1.5MIPS, and the size of the memory space of the memory allocated by the first terminal device to perform the target task may be 25M, which is to be understood that this is only for convenience of understanding the present solution, and is not limited to this solution.
If the number of the neural network layers deployed on the terminal devices of different types may be different, and the number of the neural network layers deployed on the terminal devices of different types in the same type may also be different, a second mapping relationship may be configured on the server, where the number of the neural network layers corresponding to at least one type of each type of terminal device may be stored in the second mapping relationship, and when the server needs to deploy the first neural network and the second neural network to a new first terminal device, two split nodes corresponding to the first terminal device of the target type may be determined according to the target type, and the second mapping relationship of the new first terminal device.
Before executing step 401, when a part of the neural network layers in the target neural network needs to be deployed on the first terminal device, a first request may be sent to the server, where the first request is used to request to acquire the part of the neural network layers in the target neural network, and the first request further carries a target type of the first terminal device and a target model of the first terminal device. The server can receive the target type of the first terminal equipment and the target model of the first terminal equipment, and acquire two split nodes corresponding to the target type and the target model from the second mapping relation; and splitting the first neural network and the third neural network from the target neural network by the server according to the acquired two splitting nodes.
The second mapping relationship may be stored on the server in a table, an array, or other form. For a more intuitive understanding of the present solution, the second mapping relationship is shown in the form of a table below.
TABLE 3 Table 3
As shown in table 3, for two first terminal devices of the same type and different models, the two split nodes corresponding to the target neural network may be the same or different. For example, when two different terminal devices appear as different models of lights, the number of neural network layers deployed by the target neural network deployed on all models of lights is the same. When two different terminal devices are respectively a mobile phone of model 0001 and a mobile phone of model 0004, the number of the neural network layers deployed by the target neural network deployed on the two different terminal devices is different, and the example in table 3 is only for facilitating understanding of the content in the second mapping relationship, and is not used for limiting the scheme.
More specifically, in one implementation, the second mapping relationship is sent to the server by the other device. In another implementation, the second mapping is generated by a server.
Further, the determining factors of the first neural network and the third neural network in the second mapping relationship may include any one or a combination of the following factors: when the first terminal device performs the target task, a pre-estimate of the processor resources allocated by the first terminal device, a pre-estimate of the memory resources allocated by the first terminal device, or other types of factors, etc.
That is, the server may acquire the above-mentioned index of the first terminal device of each model of the at least one model of each type, generate the number of neural network layers deployed on the first terminal device of the target model of a certain target type according to the above-mentioned index of the first terminal device of each model of the at least one model of each type, and repeatedly perform the above-mentioned operations to generate the second mapping relationship. The more the pre-estimated amount of the processor resources allocated by the first terminal device is, the more the number of the neural network layers allocated on the first terminal device is, and the less the pre-estimated amount of the processor resources allocated by the first terminal device is, the fewer the number of the neural network layers allocated on the first terminal device is. The more the pre-estimated amount of memory resources allocated by the first terminal device is, the more the number of neural network layers allocated on the first terminal device is, and the fewer the pre-estimated amount of memory resources allocated by the first terminal device is, the fewer the number of neural network layers allocated on the first terminal device is.
For understanding of the two concepts of "the estimated amount of the processor resource allocated by the first terminal device" and "the estimated amount of the memory resource allocated by the first terminal device" reference may be made to the above description, and details are not repeated here.
In another implementation manner, in the case that the first terminal device is the first terminal device and the first terminal device is the second terminal device, the split nodes corresponding to the target neural network may be the same, that is, the number of the neural network layers deployed by the target neural network deployed on the different first terminal devices may be the same.
402. The first terminal equipment inputs the data to be processed into the first neural network to obtain a first intermediate result generated by the first neural network.
In the embodiment of the present application, step 401 is an optional step, and if step 401 is executed, the first terminal device may receive the first neural network and the third neural network sent by the server, and store the received first neural network and third neural network locally.
If step 401 is not performed, in one implementation, if the first neural network, the second neural network, and the third neural network are obtained by splitting the target neural network, the server may send the first P neural network layers in the target neural network and the last Q neural network layers in the target neural network to the first terminal device, and send the first indication information to the first terminal device; wherein P is an integer greater than or equal to N, Q is an integer greater than or equal to S, and the first indication information is used for informing the first terminal equipment of the positions of the two split nodes corresponding to the target neural network in the target neural network.
The first terminal equipment stores the received first P neural network layers and the received last Q neural network layers locally, determines a first neural network from the first P neural network layers according to the received first indication information, and determines a third neural network from the last Q neural network layers, namely the first neural network and the third neural network are deployed on the first terminal equipment.
In another implementation manner, the server may further send the trained entire target neural network to the first terminal device, and send first indication information to the first terminal device, where the first indication information is used to inform the first terminal device of positions of two split nodes corresponding to the target neural network in the target neural network. Therefore, the first terminal equipment can split the received target neural network according to the received first indication information to determine the first neural network and the third neural network, namely the first neural network and the third neural network are deployed on the first terminal equipment.
After the first neural network and the third neural network are deployed, the first terminal device may input the data to be processed into the first neural network, so as to obtain a first intermediate result generated by the first neural network. Wherein the data to be processed is embodied as what type of data is related to what type of task is embodied as a target task, for example, the data to be processed may be embodied as any of the following data: sound data, image data, fingerprint data, profile data of ears, sequence data capable of reflecting user habits, text data, point cloud data or other types of data, etc., it should be understood that what type of data is employed for the data to be processed needs to be determined in connection with what type of task is the target task performed through the target neural network, and is not limited herein. In the implementation mode, various expression forms of the data to be processed are provided, the application scene of the scheme is expanded, and the implementation flexibility of the scheme is improved.
The "first intermediate result generated by the first neural network" may also be referred to as "first hidden vector generated by the first neural network", where the first intermediate result generated by the first neural network includes data required for the data processing by the second neural network.
Further, in one case, the "first intermediate result generated by the first neural network" includes data generated by a last neural network layer in the first neural network. For a more intuitive understanding of the present solution, please refer to fig. 6, fig. 6 is a schematic diagram of a first intermediate result in the data processing method according to an embodiment of the present application. As shown in fig. 6, the first intermediate result includes data generated by the last neural network layer in the first neural network (i.e., the third convolutional layer in fig. 6), and it should be understood that the example in fig. 6 is merely for convenience of understanding the present solution, and is not limited to the present solution.
In another case, the "first intermediate result generated by the first neural network" includes data generated by the last neural network layer in the first neural network and data generated by other neural network layers in the first neural network. For a more intuitive understanding of the present solution, please refer to fig. 7, fig. 7 is another schematic diagram of a first intermediate result in the data processing method according to an embodiment of the present application. The two split nodes corresponding to the target neural network shown in fig. 7 are identical to the two split nodes corresponding to the target neural network shown in fig. 5, and as shown in fig. 7, the first intermediate result includes not only data generated by the last neural network layer (i.e., the 5 th convolutional layer in fig. 7) in the first neural network, but also data generated by the N-2 nd neural network layer (i.e., the 3 rd convolutional layer in fig. 7) in the first neural network, and it should be understood that the example in fig. 7 is only for facilitating understanding of the present scheme, and is not limited to the present scheme.
403. The first terminal device sends the first intermediate result to the server.
In the embodiment of the application, after the first intermediate result is obtained, the first terminal device can encrypt the first intermediate result and send the encrypted first intermediate result to the server. Among other encryption algorithms employed include, but are not limited to, secure socket layer (secure sockets layer, SSL) encryption algorithms or other types of encryption algorithms, and the like.
404. The server inputs the first intermediate result into the second neural network to obtain a second intermediate result generated by the second neural network.
In the embodiment of the application, after receiving the encrypted first intermediate result, the server can decrypt the encrypted first intermediate result to obtain the first intermediate result, and input the first intermediate result into the second neural network to obtain the second intermediate result generated by the second neural network.
The "second intermediate result generated by the second neural network" may also be referred to as "second hidden vector generated by the second neural network", and the second intermediate result generated by the second neural network includes data required for data processing by the third neural network.
Further, in one case, the "second intermediate result generated by the second neural network" includes data generated by the last neural network layer in the second neural network. For a more visual understanding of the present solution, please understand with reference to fig. 7, as shown in fig. 7, the second splitting node corresponding to the target neural network (i.e., the splitting node between the second neural network and the third neural network) is located between the pooling layer and the first linear connection layer, and then the second intermediate result includes the data generated by the last neural network layer in the second neural network (i.e., the pooling layer in fig. 7), which should be understood that the example in fig. 7 is only for facilitating understanding of the present solution, and is not limited to this solution.
In another case, the "second intermediate result generated by the second neural network" includes data generated by the last neural network layer in the second neural network and data generated by other neural network layers in the second neural network. Referring to fig. 8, fig. 8 is another schematic diagram of a second intermediate result in the data processing method according to the embodiment of the application. As shown in fig. 8, the second intermediate result includes not only the data generated by the last neural network layer in the second neural network (i.e., the last convolutional layer in fig. 8), but also the data generated by the M-2 nd neural network layer in the second neural network (i.e., the 3 rd convolutional layer in fig. 8), and it should be understood that the example in fig. 8 is only for convenience of understanding the present solution, and is not limited to the present solution.
405. The server sends the second intermediate result to the first terminal device.
In the embodiment of the present application, after obtaining the second intermediate result, the server may encrypt the second intermediate result and send the encrypted second intermediate result to the first terminal device, and the encryption algorithm specifically adopted may refer to the description in step 403, which is not described herein.
406. The first terminal device inputs the second intermediate result into a third neural network to obtain a prediction result which is generated by the third neural network and corresponds to the data to be processed, and the type of information indicated by the prediction result corresponds to the type of the target task.
In the embodiment of the application, after receiving the encrypted second intermediate result, the first terminal device may input the second intermediate result into the third neural network, that is, input the second intermediate result into the last S neural network layers of the target neural network, to obtain a prediction result corresponding to the data to be processed generated by the third neural network (that is, obtain a prediction result corresponding to the data to be processed output by the whole target neural network).
The type of the information indicated by the prediction result corresponding to the data to be processed corresponds to the type of the target task. As an example, if the target task is voiceprint recognition, the data to be processed may be voice data, and the prediction result corresponding to the data to be processed is used to indicate whether the data to be processed (i.e., voice data) is a preset user voice. As another example, for example, if the target task is voiceprint feature extraction, the data to be processed may be sound data, and the prediction result corresponding to the data to be processed is voiceprint feature extracted from the data to be processed.
As another example, for example, the target task is face recognition, the data to be processed may be image data of a face of a user, and the prediction result corresponding to the data to be processed is used to indicate whether the user is a preset user. As another example, for example, the target task is fingerprint recognition, the data to be processed is fingerprint data of a user, and the prediction result corresponding to the data to be processed is used to indicate whether the user is a preset user. As yet another example, for example, the objective task is to perform feature extraction on the contour data of the ear of the user, the data to be processed is the contour data of the ear of the user, the prediction result corresponding to the data to be processed is the feature of the contour data of the ear of the user, and the like, and the prediction result corresponding to the data to be processed is not exhaustive here.
The processor resources occupied by the first terminal equipment in the process of data processing through the first neural network and the third neural network are smaller than the processor resources occupied by the server in the process of data processing through the second neural network, and the memory resources occupied by the first terminal equipment in the process of data processing through the first neural network and the third neural network are smaller than the memory resources occupied by the server in the process of data processing through the second neural network.
In the embodiment of the application, the second neural network is deployed on the server, and the second neural network occupies more processor resources and more memory resources in the process of data processing, so that the computer resources of the first terminal equipment occupied in the whole calculation process of the neural network can be further reduced, and the calculation pressure of the first terminal equipment in the process of executing the target task can be reduced; because most of calculation in the data processing process of the whole neural network is executed by the server, the deep neural network with more parameters can be adopted to generate the prediction result fixed with the data to be processed, and the accuracy of the prediction result generated by the whole neural network is improved.
In the embodiment of the present application, after obtaining the prediction result corresponding to the data to be processed, the first terminal device may execute subsequent steps according to the prediction result corresponding to the data to be processed, and specifically execute which steps may be determined in combination with the actual application scenario, which is not limited herein.
For a more intuitive understanding of the present solution, please refer to fig. 9, fig. 9 is a flow chart of a data processing method according to an embodiment of the present application. In fig. 9, taking a target task executed by a target neural network as extraction of voiceprint features, and splitting the target neural network by the first neural network, the second neural network and the third neural network is taken as an example, as shown in fig. 9, B1 and the first terminal device acquire data to be processed input by a user (i.e., voice data input by the user shown in fig. 9). B2, the first terminal equipment inputs the data to be processed into a first neural network (namely the first N neural network layers of the target neural network shown in fig. 9), and a first intermediate result generated by the first neural network is obtained. And B3, the first terminal equipment encrypts the first intermediate result and sends the encrypted first intermediate result to the server so as to realize encrypted transmission of the first intermediate result. And B4, the server decrypts the encrypted first intermediate result to obtain a first intermediate result, and inputs the first intermediate result into a second neural network (namely M neural network layers after N neural network layers) to obtain a second intermediate result generated by the second neural network. And B5, the server encrypts the second intermediate result and sends the encrypted second intermediate result to the first terminal equipment so as to realize encrypted transmission of the second intermediate result. And B6, the first terminal equipment decrypts the encrypted second intermediate result to obtain a second intermediate result, and inputs the second intermediate result into a third neural network (namely, the last S neural network layers of the target neural network) to obtain a prediction result (namely, voiceprint characteristics extracted from the input voice data) which is output by the whole target neural network and corresponds to the data to be processed. B7, the first terminal device compares each voiceprint feature in the locally stored at least one voiceprint feature with the acquired voiceprint features to determine whether the acquired voiceprint feature is any one of the at least one voiceprint features stored in advance, so as to determine whether the user is a user with authority, and it should be understood that the example in FIG. 9 is only for facilitating understanding of the scheme and is not intended to limit the scheme.
407. The server obtains updated split nodes corresponding to the target neural network, wherein the updated split nodes indicate that the first neural network comprises n neural network layers, the second neural network comprises m neural network layers and the third neural network comprises s neural network layers.
In some embodiments of the present application, after the first neural network and the third neural network are deployed on one determined first terminal device, the server may obtain updated split nodes corresponding to the target neural network (i.e., the neural network to which the neural network layer deployed on the first terminal device belongs), that is, at two different moments, i.e., a first moment and a second moment, where the neural network deployed on the first terminal device has the following changes: the number of neural network layers in the first neural network is changed, or the number of neural network layers in the third neural network is changed, that is, at two different times, i.e., the first time and the second time, different from the split node corresponding to the target neural network.
It should be noted that, in this solution, when the same first terminal device is at two different times, that is, the first time and the second time, the split node corresponding to the target neural network may be different, but not represent that the number of the neural network layers deployed by the target neural network is different for any two different times of the same first terminal device.
The meaning of the "the split node corresponding to the target neural network is different" may refer to the description in the above step, where the updated split node indicates that the first neural network includes N neural network layers, the second neural network includes m neural network layers, and the third neural network includes S neural network layers, the first neural network and the third neural network are deployed on the first terminal device, the second neural network is deployed on the server, N, S and m are integers greater than or equal to 1, N and N are different and/or S and S are different.
Further, the positional relationship between the "first neural network" and the "second neural network" in the target neural network, and the positional relationship between the "second neural network" and the "third neural network" in the target neural network may refer to the description in step 401, which is not repeated herein.
In the embodiment of the application, because an attacker may reversely push to obtain the original data to be processed according to the obtained intermediate result after obtaining the intermediate result sent between the first terminal device and the server, and for the two different moments of the first moment and the second moment, the split nodes corresponding to the neural network are different, namely, different intermediate results are sent between the first terminal device and the server at different moments, the difficulty of the attacker in obtaining the original data to be processed is further increased, and the protection degree of privacy of user data is further improved.
And acquiring the trigger point of the updated split node corresponding to the target neural network aiming at the server. In one implementation, the server may reacquire split nodes corresponding to the target neural network every fixed time period; by way of example, the fixed duration may be, for example, one day, one week, ten days, fifteen days, one month or other length, etc., and is not exhaustive herein.
In another implementation, the server may reacquire the split node corresponding to the target neural network at a fixed point in time; as an example, the fixed point in time may be, for example, 2 a.m. 1 of each month, 3 a.m. on monday of each week, or other point in time, etc., which is not exhaustive herein.
In another implementation manner, the first terminal device may send a request message to the server, where the request message is used to request to update the number of the neural network layers deployed by the target neural network, that is, to request to update the deployment situation of the plurality of the neural network layers included in the target neural network on the first terminal device and the server. Alternatively, the request message may be actively triggered by the user through the first terminal device, i.e. the user may actively trigger updating the number of neural network layers deployed by the target neural network, etc.
Further, in one case, the first terminal device may send a request message to the server each time the target task needs to be performed, the request message being used to request updating of the number of neural network layers deployed by the target neural network; in another case, the first terminal device may send a request message to the server for requesting updating of the number of neural network layers deployed by the target neural network every time the target task is performed a target number of times; or may trigger the first terminal device to send the request message to the server in other cases, which is not exhaustive here.
It should be noted that other ways may also exist to trigger the server to obtain the updated split node corresponding to the target neural network, and the specific implementation manner may be flexibly determined in combination with the specific application scenario, which is not limited herein.
And acquiring a specific realization process of the updated split node corresponding to the target neural network aiming at the server. The determining factors of the number of the neural network layers deployed on the first terminal device may include: the processor resource occupancy of the first terminal device and/or the memory resource occupancy of the first terminal device. Optionally, the determining factors of the first neural network and the third neural network may further include any one or more of the following: the number of processes currently running on the first terminal device, the time that each process on the first terminal device has run, the running state of each process on the first terminal device, or other factors that can be considered, may be specifically determined in conjunction with the actual application scenario, and are not listed here.
Further, the evaluation index of the "occupation amount of the memory resource of the first terminal device" may include any one or more of the following indexes: the size of the total memory resource of the first terminal device, the size of the occupied memory resource of the first terminal device, the occupancy rate of the memory resource of the first terminal device or other evaluation indexes, etc.
The evaluation index of the "occupation amount of the processor resource of the first terminal device" may include any one or more of the following: the occupation rate of the processor resources of the first terminal device, the occupation duration of each processor on the first terminal device for executing the target task, the load of the processor on the first terminal device for executing the target task allocation, the performance of the processor on the first terminal device for executing the target task allocation, or other evaluation indexes capable of reflecting the occupation amount of the processor resources on the first terminal device for executing the target task, etc. are specifically determined by combining with actual products, and are not exhaustive herein.
Specifically, the server may calculate, according to the amount of occupation of the processor resources of the first terminal device, an estimated amount of the processor resources allocated when the first terminal device executes the target task; correspondingly, the server can calculate the available amount of the memory resources of the first terminal device according to the occupied amount of the memory resources of the first terminal device, and further can obtain the pre-estimated amount of the memory resources allocated when the first terminal device executes the target task.
The server may generate an updated split node corresponding to the target neural network based on the estimated amount of processor resources allocated when the first terminal device performs the target task and the estimated amount of memory resources allocated when the first terminal device performs the target task. If the target neural network is split according to the updated splitting node corresponding to the target neural network, processor resources occupied by the first neural network and the third neural network deployed on the first terminal device in the data processing process are smaller than or equal to the estimated amount of the processor resources allocated when the first terminal device executes the target task; the memory resources occupied by the first neural network and the third neural network deployed on the first terminal device in the data processing process are less than or equal to the pre-estimated amount of memory resources allocated when the first terminal device executes the target task.
More specifically, the process of "the server obtains an estimated amount of processor resources allocated when the first terminal device performs the target task according to the amount of occupied processor resources of the first terminal device" is aimed at. In one implementation, a regression model for performing the training operation may be stored on the server, where the regression model is used to perform the estimating operation; by way of example, the regression model may employ an autoregressive moving average (autoregressive integrated moving average, ARIMA) model, a recurrent neural network (recursive neural network, RNN) or other type of model, or the like, as examples and not exhaustive herein. The input of the regression model may include an occupancy rate of a processor resource on the first terminal device, a utilization rate of a memory resource on the first terminal device, a number of processes currently running on the first terminal device, and a time that each process on the terminal has been running; the output of the regression model may be the estimated occupancy of the processor resource and the estimated occupancy of the memory resource corresponding to each process in a future period of time.
The server may calculate the estimated available amount of the processor resource and the estimated available amount of the memory resource of the first terminal device in a future period according to the estimated occupancy rate of the processor resource and the estimated occupancy rate of the memory resource corresponding to each process in the future period. Further, in one case, the server may determine the estimated availability of the processor resource of the first terminal device in the future period of time as an estimated amount of the processor resource allocated when the first terminal device performs the target task, and determine the estimated availability of the memory resource of the first terminal device in the future period of time as an estimated amount of the memory resource allocated when the first terminal device performs the target task.
In another case, the server may multiply the estimated available amount of the processor resource of the first terminal device with the first ratio in the future period of time, and determine the obtained product as the estimated amount of the processor resource allocated when the first terminal device performs the target task; multiplying the estimated available amount of the memory resource of the first terminal device in the future period of time by the first proportion, and determining the obtained product as the estimated amount of the memory resource allocated when the first terminal device executes the target task; wherein the first ratio is less than 1.
In another implementation manner, the server may also determine, according to a preset rule, an estimated amount of the allocated processor resource when the first terminal device executes the target task. The server may multiply the current occupancy of the processor resource of the first terminal device by the second ratio, and determine the obtained product as an estimated occupancy of the processor resource of the first terminal device in a future period of time; multiplying the current occupation amount of the memory resources of the first terminal equipment by the second proportion, and determining the obtained product as the estimated occupation amount of the memory resources of the first terminal equipment in a future period of time; the second ratio is greater than 1.
The server determines the estimated available amount of the processor resource of the first terminal equipment in a future period according to the estimated occupied amount of the processor resource of the first terminal equipment in the future period; and determining the estimated available amount of the memory resource of the first terminal equipment in a future period according to the estimated occupied amount of the memory resource of the first terminal equipment in the future period. Further, the estimated amount of the allocated processor resources and the estimated amount of the memory resources when the first terminal device executes the target task can be determined according to the estimated available amount of the processor resources and the estimated available amount of the memory resources of the first terminal device in a future period.
It should be noted that, the description of "the server obtains the predicted amount of the processor resource allocated when the first terminal device performs the target task according to the occupied amount of the processor resource of the first terminal device" is merely to prove the feasibility of the solution, and the server may also obtain the predicted amount of the processor resource allocated when the first terminal device performs the target task in other manners, which is not exhaustive in each implementation here.
Optionally, in order to enable the updated split node of the target neural network is different from the split node before the update. In one implementation, after generating the updated split node corresponding to the target neural network according to the estimated amount of the processor resource allocated when the first terminal device executes the target task and the estimated amount of the memory resource allocated when the first terminal device executes the target task, the server may randomly adjust the determined split node, that is, randomly forward or backward move the position of the split node in the target neural network, so as to update the updated split node corresponding to the target neural network again, to obtain the final updated split node corresponding to the target neural network.
Further, in the embodiment corresponding to fig. 4, two split nodes are corresponding to the target neural network, so when the determined split nodes are randomly adjusted, only the position of the first split node in the target neural network can be randomly adjusted, and only the position of the second split node in the target neural network can be randomly adjusted; the positions of the first split node and the second split node in the target neural network can be randomly adjusted.
In order to more intuitively understand the solution, referring to fig. 10, fig. 10 is a schematic flow chart of updating a splitting node corresponding to a target neural network in the embodiment of the present application, fig. 10 is a flowchart of splitting the target neural network by using a first neural network, a second neural network and a third neural network, and as shown in fig. 10, C1, when a first terminal device has not performed a target task, acquires a plurality of parameters associated with a computer resource already occupied on the first terminal device, where the plurality of parameters may include a occupation amount of a processor resource of the first terminal device, a occupation amount of a memory resource of the first terminal device, a number of processes currently running on the first terminal device and a time that each process has run on the first terminal device, and the first terminal device sends the plurality of parameters to a server; the server determines the estimated amount of the allocated processor resources and the estimated amount of the memory resources when the first terminal equipment executes the target task according to the received multiple parameters; the server obtains updated split nodes corresponding to the target neural network according to the estimated amount of the processor resources and the estimated amount of the memory resources allocated by the first terminal equipment when the target task is executed; c4, the server randomly forwards or backwards moves the updated split node corresponding to the target neural network to obtain a final updated split node corresponding to the target neural network; c5, the server determines n neural network layers included in the first neural network, m neural network layers included in the second neural network and s neural network layers included in the third neural network from the target neural network according to the final updated split node corresponding to the target neural network; and C6, the server sends n neural network layers included in the first neural network and s neural network layers included in the third neural network to the first terminal device so as to deploy the first neural network and the third neural network to the first terminal device and deploy the second neural network to the server, and it should be understood that the example in fig. 10 is only for facilitating understanding of the present solution, and is not used for limiting the present solution.
In another implementation manner, the server may adopt different prediction algorithms at different moments, and obtain, according to the available amount of the processor resources of the first terminal device, the predicted amount of the processor resources allocated when the first terminal device executes the target task, so as to improve the probabilities of different predicted amounts of the processor resources corresponding to different moments; correspondingly, the server can adopt different pre-estimation algorithms at different moments, and according to the available amount of the memory resources of the first terminal equipment, the pre-estimated amount of the memory resources allocated when the first terminal equipment executes the target task is obtained, so that the probability of different pre-estimated amounts of the memory resources corresponding to different moments is improved. Thereby improving the probability of different numbers of the neural network layers deployed by the targets corresponding to different moments.

Optionally, the storage unit is a storage unit in the chip, such as a register, a cache, etc., and the storage unit may also be a storage unit in the wireless access device side located outside the chip, such as a read-only memory (ROM) or other type of static storage device that may store static information and instructions, a random access memory (random access memory, RAM), etc.
Specifically, referring to fig. 20, fig. 20 is a schematic structural diagram of a chip provided in an embodiment of the present application, where the chip may be represented as a neural network processor NPU 200, and the NPU 200 is mounted as a coprocessor on a main CPU (Host CPU), and the Host CPU distributes tasks. The core part of the NPU is an arithmetic circuit 2003, and the controller 2004 controls the arithmetic circuit 2003 to extract matrix data in the memory and perform multiplication.
In some implementations, the arithmetic circuit 2003 internally includes a plurality of processing units (PEs). In some implementations, the operational circuit 2003 is a two-dimensional systolic array. The operation circuit 2003 may also be a one-dimensional systolic array or other electronic circuit capable of performing mathematical operations such as multiplication and addition. In some implementations, the operational circuit 2003 is a general-purpose matrix processor.
For example, assume that there is an input matrix a, a weight matrix B, and an output matrix C. The arithmetic circuit takes the data corresponding to matrix B from the weight memory 2002 and buffers it on each PE in the arithmetic circuit. The arithmetic circuit takes matrix a data and matrix B from the input memory 2001, performs matrix operation, and the obtained partial result or final result of the matrix is stored in an accumulator (accumulator) 2008.
The unified memory 2006 is used for storing input data and output data. The weight data is carried directly to the weight memory 2002 by the memory cell access controller (Direct Memory Access Controller, DMAC) 2005. The input data is also carried into the unified memory 2006 through the DMAC.
BIU is Bus Interface Unit, i.e., bus interface unit 2010, for the AXI bus to interact with DMAC and finger memory (Instruction Fetch Buffer, IFB) 2009.
The bus interface unit 2010 (Bus Interface Unit, abbreviated as BIU) is configured to obtain an instruction from the external memory by the instruction fetch memory 2009, and further configured to obtain the raw data of the input matrix a or the weight matrix B from the external memory by the storage unit access controller 2005.
The DMAC is mainly used to transfer input data in the external memory DDR to the unified memory 2006 or to transfer weight data to the weight memory 2002 or to transfer input data to the input memory 2001.
The vector calculation unit 2007 includes a plurality of operation processing units that perform further processing on the output of the operation circuit, such as vector multiplication, vector addition, exponential operation, logarithmic operation, magnitude comparison, and the like, as necessary. The method is mainly used for non-convolution/full-connection layer network calculation in the neural network, such as Batch Normalization (batch normalization), pixel-level summation, up-sampling of a characteristic plane and the like.
In some implementations, the vector calculation unit 2007 can store the vector of processed outputs to the unified memory 2006. For example, the vector calculation unit 2007 may apply a linear function and/or a nonlinear function to the output of the operation circuit 2003, for example, linearly interpolate the feature plane extracted by the convolution layer, and further, for example, accumulate a vector of values to generate an activation value. In some implementations, the vector calculation unit 2007 generates normalized values, pixel-level summed values, or both. In some implementations, the vector of processed outputs can be used as an activation input to the operational circuitry 2003, e.g., for use in subsequent layers in a neural network.
A fetch memory (instruction fetch buffer) 2009 connected to the controller 2004 for storing instructions used by the controller 2004;
the unified memory 2006, the input memory 2001, the weight memory 2002, and the finger memory 2009 are all On-Chip memories. The external memory is proprietary to the NPU hardware architecture.
