Description

Method for generating a dataset {METHOD FOR GENERATING DATA SET}

This disclosure relates to artificial intelligence technology, and more specifically, to a method for generating a dataset for an artificial intelligence-based model.

In recent years, machine-learning technology, including deep-learning, has received attention by showing results that exceed the performance of existing methods in analyzing various types of data such as video, voice, and text. In addition, machine learning technology is being introduced and utilized in various fields due to the scalability and flexibility inherent in the technology itself.

Among the various fields where machine learning technology can be applied, the image-related field is one of the fields that is most actively introducing machine learning technology in various detailed fields such as object recognition and object classification.

Visual localization refers to a technology that identifies the surrounding environment through a camera and determines where the camera user is currently located based on this. This visual positioning can estimate in real time the location of the user who took the image and the direction the camera is looking (camera pose) from the image. Such visual localization can, for example, analyze an image captured by a camera by obtaining feature points from the image using a model for visual localization.

As described above, in order to obtain accurate feature points from an image using a model for visual localization, it is necessary to preemptively secure a dataset for learning and verifying the model for visual localization.

A neural network consists of at least one node. Nodes (or neurons) that make up neural networks may be interconnected by one or more links.

Within a neural network, one or more nodes connected through a link may form a relative input node and output node relationship. The concepts of input node and output node are relative, and any node in an output node relationship with one node may be in an input node relationship with another node, and vice versa. As described above, input node to output node relationships can be created around links. One or more output nodes can be connected to one input node through a link, and vice versa.

In a relationship between an input node and an output node connected through one link, the value of the data of the output node may be determined based on the data input to the input node. Here, the link connecting the input node and the output node may have a weight. Weights may be variable and may be varied by the user or algorithm in order for the neural network to perform the desired function. For example, when one or more input nodes are connected to one output node by respective links, the output node is set to the values input to the input nodes connected to the output node and the links corresponding to each input node. The output node value can be determined based on the weight.

As described above, in a neural network, one or more nodes are interconnected through one or more links to form an input node and output node relationship within the neural network. The characteristics of the neural network can be determined according to the number of nodes and links within the neural network, the correlation between the nodes and links, and the value of the weight assigned to each link. For example, if the same number of nodes and links exist and two neural networks with different weight values of the links exist, the two neural networks may be recognized as different from each other.

A neural network may consist of a set of one or more nodes. A subset of nodes that make up a neural network can form a layer. Some of the nodes constituting the neural network may form one layer based on the distances from the first input node. For example, a set of nodes with a distance n from the initial input node may constitute n layers. The distance from the initial input node can be defined by the minimum number of links that must be passed to reach the node from the initial input node. However, this definition of a layer is arbitrary for explanation purposes, and the order of a layer within a neural network may be defined in a different way than described above. For example, a layer of nodes may be defined by distance from the final output node.

The initial input node may refer to one or more nodes in the neural network through which data is directly input without going through links in relationships with other nodes. Alternatively, in a neural network network, in the relationship between nodes based on links, it may mean nodes that do not have other input nodes connected by links. Similarly, the final output node may refer to one or more nodes that do not have an output node in their relationship with other nodes among the nodes in the neural network. Additionally, hidden nodes may refer to nodes constituting a neural network other than the first input node and the last output node.

The neural network according to an embodiment of the present disclosure is a neural network in which the number of nodes in the input layer may be the same as the number of nodes in the output layer, and the number of nodes decreases and then increases again as it progresses from the input layer to the hidden layer. You can. In addition, the neural network according to another embodiment of the present disclosure may be a neural network in which the number of nodes in the input layer may be less than the number of nodes in the output layer, and the number of nodes decreases as it progresses from the input layer to the hidden layer. there is. In addition, the neural network according to another embodiment of the present disclosure may be a neural network in which the number of nodes in the input layer may be greater than the number of nodes in the output layer, and the number of nodes increases as it progresses from the input layer to the hidden layer. You can. A neural network according to another embodiment of the present disclosure may be a neural network that is a combination of the above-described neural networks.

A deep neural network (DNN) may refer to a neural network that includes multiple hidden layers in addition to the input layer and output layer. Deep neural networks allow you to identify latent structures in data. In other words, it is possible to identify the potential structure of a photo, text, video, voice, or music (e.g., what object is in the photo, what the content and emotion of the text are, what the content and emotion of the voice are, etc.) . Deep neural networks include convolutional neural network (CNN), recurrent neural network (RNN), auto encoder, restricted Boltzmann machine (RBM), and deep trust network ( It may include deep belief network (DBN), Q network, U network, Siamese network, generative adversarial network (GAN), etc. The description of the deep neural network described above is only an example and the present disclosure is not limited thereto.

A neural network may be trained in at least one of supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning. Learning of a neural network may be a process of applying knowledge for the neural network to perform a specific operation to the neural network.

Neural networks can be trained to minimize output errors. In neural network learning, learning data is repeatedly input into the neural network, the output of the neural network and the error of the target for the learning data are calculated, and the error of the neural network is transferred from the output layer of the neural network to the input layer in the direction of reducing the error. This is the process of updating the weight of each node in the neural network through backpropagation. In the case of supervised learning, learning data in which the correct answer is labeled for each learning data is used (i.e., labeled learning data), while in the case of unsupervised learning, the correct answer may not be labeled in each learning data. That is, for example, in the case of supervised learning on data classification, the training data may be data in which each training data is labeled with a category. Labeled training data is input to the neural network, and the error can be calculated by comparing the output (category) of the neural network with the label of the training data. As another example, in the case of unsupervised learning on data classification, the error can be calculated by comparing the input training data with the neural network output. The calculated error is backpropagated in the reverse direction (i.e., from the output layer to the input layer) in the neural network, and the connection weight of each node in each layer of the neural network can be updated according to backpropagation. The amount of change in the connection weight of each updated node may be determined according to the learning rate. The neural network's calculation of input data and backpropagation of errors can constitute a learning cycle (epoch). The learning rate may be applied differently depending on the number of repetitions of the learning cycle of the neural network. For example, in the early stages of neural network training, a high learning rate can be used to increase efficiency by allowing the neural network to quickly achieve a certain level of performance, and in the later stages of training, a low learning rate can be used to increase accuracy.

In the learning of neural networks, the training data can generally be a subset of real data (i.e., the data to be processed using the learned neural network), and thus the error for the training data is reduced, but the error for the real data is reduced. There may be an incremental learning cycle. Overfitting is a phenomenon in which errors in actual data increase due to excessive learning on training data. For example, a phenomenon in which a neural network that learned a cat by showing a yellow cat fails to recognize that it is a cat when it sees a non-yellow cat may be a type of overfitting. Overfitting can cause errors in machine learning algorithms to increase. To prevent such overfitting, various optimization methods can be used. To prevent overfitting, methods such as increasing the learning data, regularization, dropout that disables some of the network nodes during the learning process, and use of a batch normalization layer can be applied. there is.

According to an embodiment of the present disclosure, a computer-readable medium storing a data structure is disclosed.

Data structure can refer to the organization, management, and storage of data to enable efficient access and modification of data. Data structure can refer to the organization of data to solve a specific problem (e.g., retrieving data, storing data, or modifying data in the shortest possible time). A data structure may be defined as a physical or logical relationship between data elements designed to support a specific data processing function. Logical relationships between data elements may include connection relationships between user-defined data elements. Physical relationships between data elements may include actual relationships between data elements that are physically stored in a computer-readable storage medium (e.g., a persistent storage device). A data structure may specifically include a set of data, relationships between data, and functions or instructions applicable to the data. Effectively designed data structures allow computing devices to perform computations while minimizing the use of the computing device's resources. Specifically, computing devices can increase the efficiency of operations, reading, insertion, deletion, comparison, exchange, and search through effectively designed data structures.

Data structures can be divided into linear data structures and non-linear data structures depending on the type of data structure. A linear data structure may be a structure in which only one piece of data is connected to another piece of data. Linear data structures may include List, Stack, Queue, and Deque. A list can refer to a set of data that has an internal order. The list may include a linked list. A linked list may be a data structure in which data is connected in such a way that each data is connected in a single line with a pointer. In a linked list, a pointer may contain connection information to the next or previous data. Depending on its form, a linked list can be expressed as a singly linked list, a doubly linked list, or a circularly linked list. A stack may be a data listing structure that allows limited access to data. A stack can be a linear data structure in which data can be processed (for example, inserted or deleted) at only one end of the data structure. Data stored in the stack may have a data structure (LIFO-Last in First Out) where the later it enters, the sooner it comes out. A queue is a data listing structure that allows limited access to data. Unlike the stack, it can be a data structure (FIFO-First in First Out) where data stored later is released later. A deck can be a data structure that can process data at both ends of the data structure.

A non-linear data structure may be a structure in which multiple pieces of data are connected behind one piece of data. Nonlinear data structures may include graph data structures. A graph data structure can be defined by vertices and edges, and an edge can include a line connecting two different vertices. Graph data structure may include a tree data structure. A tree data structure may be a data structure in which there is only one path connecting two different vertices among a plurality of vertices included in the tree. In other words, it may be a data structure that does not form a loop in the graph data structure.

Throughout this specification, computational model, neural network, network function, and neural network may be used interchangeably. Below, it is described in a unified manner as a neural network. Data structures may include neural networks. And the data structure including the neural network may be stored in a computer-readable medium. Data structures including neural networks also include data preprocessed for processing by a neural network, data input to the neural network, weights of the neural network, hyperparameters of the neural network, data acquired from the neural network, activation functions associated with each node or layer of the neural network, neural network It may include a loss function for learning.

In addition to the configurations described above, a data structure containing a neural network may include any other information that determines the characteristics of the neural network. Additionally, the data structure may include all types of data used or generated in the computational process of a neural network and is not limited to the above. Computer-readable media may include computer-readable recording media and/or computer-readable transmission media. A neural network can generally consist of a set of interconnected computational units, which can be referred to as nodes. These nodes may also be referred to as neurons. A neural network consists of at least one node.

The data structure may include data input to the neural network. A data structure containing data input to a neural network may be stored in a computer-readable medium. Data input to the neural network may include learning data input during the neural network learning process and/or input data input to the neural network on which training has been completed. Data input to the neural network may include data that has undergone pre-processing and/or data subject to pre-processing. Preprocessing may include a data processing process to input data into a neural network. Therefore, the data structure may include data subject to preprocessing and data generated by preprocessing. The above-described data structure is only an example and the present disclosure is not limited thereto.

The data structure may include the weights of the neural network. (In this specification, weights and parameters may be used with the same meaning.) And the data structure including the weights of the neural network may be stored in a computer-readable medium. A neural network may include multiple weights. Weights may be variable and may be varied by the user or algorithm in order for the neural network to perform the desired function. For example, when one or more input nodes are connected to one output node by respective links, the output node is set to the values input to the input nodes connected to the output node and the links corresponding to each input node. Based on the weight, the data value output from the output node can be determined. The above-described data structure is only an example and the present disclosure is not limited thereto.

As an example and not a limitation, the weights may include weights that are changed during the neural network learning process and/or weights for which neural network learning has been completed. Weights that change during the neural network learning process may include weights that change at the start of the learning cycle and/or weights that change during the learning cycle. Weights for which neural network training has been completed may include weights for which a learning cycle has been completed. Therefore, the data structure including the weights of the neural network may include weights that are changed during the neural network learning process and/or the data structure including the weights for which neural network learning has been completed. Therefore, the above-mentioned weights and/or combinations of each weight are included in the data structure including the weights of the neural network. The above-described data structure is only an example and the present disclosure is not limited thereto.

The data structure including the weights of the neural network may be stored in a computer-readable storage medium (e.g., memory, hard disk) after going through a serialization process. Serialization can be the process of converting a data structure into a form that can be stored on the same or a different computing device and later reorganized and used. Computing devices can transmit and receive data over a network by serializing data structures. Data structures containing the weights of a serialized neural network can be reconstructed on the same computing device or on a different computing device through deserialization. The data structure including the weights of the neural network is not limited to serialization. Furthermore, the data structure including the weights of the neural network is a data structure to increase computational efficiency while minimizing the use of computing device resources (e.g., in non-linear data structures, B-Tree, Trie, m-way search tree, AVL tree, Red-Black Tree) may be included. The foregoing is merely an example and the present disclosure is not limited thereto.

It may include a number (e.g., number of hidden layers, number of nodes in hidden layers). The above-described data structure is only an example and the present disclosure is not limited thereto.

3A and 3B are diagrams for explaining a model for visual location of a computing device according to some embodiments of the present disclosure.

The processor 110 may obtain feature information including feature point information by inputting the image included in the input data into a model for visual localization. For example, a model for visual localization uses a dataset to compare the first feature point obtained from the first image included in the first image information and the second feature point obtained from the second image included in the second image information. It can be learned to respond. Here, the first image and the second image may be images of the first area acquired in different environments. Accordingly, when images of corresponding areas are input to the model for visual localization, the processor 110 may train the model for visual localization so that feature point information obtained from the images corresponds to each other.

Feature point information may include at least one feature point and/or descriptor. At least one feature point may be a coordinate for each characteristic part of the image. At least one descriptor may include information for describing each of at least one feature point. For example, at least one descriptor may include information about the directionality and size of each of the at least one feature point and/or the relationship between pixels surrounding each of the at least one feature point.

Referring to FIG. 3A , the processor 110 may obtain first feature point information 30 by inputting the first image 11 into the model 20 for visual localization. The first feature point information 30 may include a first feature point 31 and a first descriptor 32. The first feature point 31 may be the coordinates of the first part that is a feature in the first image. The first descriptor 32 may include information for describing the first feature point.

Referring to FIG. 3B, the processor 110 may obtain second feature point information 40 by inputting the second image 12 into the model 20 for visual localization. The second feature point information 40 may include a second feature point 41 and a second descriptor 42. The second feature point 41 may be the coordinates of the first part that is a feature in the second image. The second descriptor 42 may include information for describing the second feature point.

Referring to FIGS. 3A and 3B , the first image 11 and the second image 12 may be images taken of corresponding areas in different environments. Accordingly, the processor 110 uses the dataset to determine a plurality of first feature points obtained from the first image 11 included in the first image information and the second image 12 included in the second image information. The model 20 for visual localization can be trained so that the two acquired feature points correspond to each other.

For example, the first image 11 and the second image 12 are images taken of corresponding areas and may have different time information. In this case, the processor 110 can learn the model 20 for visual positioning by comparing a plurality of first feature points and a plurality of second feature points so that points with coordinates that do not correspond to each other are recognized as common feature points. . Specifically, when the first coordinate point that exists in the plurality of first feature points does not exist in the plurality of second feature points, the processor 110 selects the first coordinate point as one feature point among the plurality of second feature points. The model 20 for visual localization can be trained to be included.

For another example, the first image 11 and the second image 12 are images taken of corresponding areas and may have different lighting information. In this case, the processor 110 may compare at least one overlapping point between the plurality of first feature points and the plurality of second feature points. And, if the position difference between the duplicate points is less than or equal to a preset threshold, the processor 110 sets the loss function so that the first descriptor 32 and the second descriptor 42 corresponding to the duplicate point are close to each other. You can learn it by doing this.

The processor 110 may train the model 20 for visual localization not to extract feature points from moving objects and/or variable elements other than the basic object. For example, the model 20 for visual localization may include an object detection algorithm, a segmentation algorithm, etc. The model 20 for visual localization recognizes moving objects and/or variable elements using object detection algorithms, segmentation algorithms, etc., and feature points extracted from moving objects and/or variable elements are feature points. It can be learned not to be included in information. Here, the processor 110 uses the model 20 for visual positioning including an object detection algorithm to distinguish the type (class) of the object in the input image, and the type of the object is a moving object and/or a variable element. The feature points extracted from can obtain the removed feature point information. According to some embodiments of the present disclosure, the processor 110 classifies objects in the input image using the model 20 for visual localization including a segmentation algorithm, and determines the location of the object that is a moving object and/or variable element. The feature points extracted from the corresponding location can be used to obtain information on the removed feature points.

When images of corresponding areas in different environments are input to the model for visual localization, the processor 110 can train the model so that feature points obtained from each of the images correspond to each other. Since the model for visual localization is learned from a dataset created using 3D models with different environments, feature points can be obtained consistently even with changes in time and light.

Referring to FIG. 5, the processor 110 may generate a third environment of the 3D model based on third state information that is different from the second state information (S210). The third state information may be different from the first state information and the second state information.

The processor 110 may acquire fourth image information about the first area of the 3D model to which the fourth environment is applied (S240).

The processor 110 may generate a dataset of a model for visual localization based on the third image information and the fourth image information (S250).

As described above with reference to FIG. 5, the processor 110 applies different environments created based on different state information to the 3D model to generate a dataset using images of different environments in the same area. can do.

Referring to FIG. 6, the processor 110 may obtain fifth image information for the second area of the 3D model to which the first environment is applied (S310). The second area may be a different area that does not overlap with the first area. According to an embodiment of the present disclosure, the second area may be an area that only partially overlaps with the first area. For example, the first part of the second area and the first part of the first area may overlap each other, and the second part of the second area and the second part of the first area may not overlap each other.

The processor 110 may acquire sixth image information about the second area of the 3D model to which the second environment is applied (S320).

The processor 110 may generate a dataset of a model for visual positioning based on the fifth image information and the sixth image information (S330).

As described above with reference to FIG. 6, the processor 110 may generate a dataset using images of different environments in various areas. For example, the processor 110 acquires images of each of a plurality of different regions in the 3D model to which the first environment is applied, and acquires images of each of a plurality of different regions from the 3D model to which the second environment is applied.
