Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, a data processing method according to an embodiment of the present application includes the following steps:
s101, determining a variable set to be selected and variable values thereof according to specific service data of a first user group; the first user group comprises a user group provided with a data processing mode of a specific service.
In the embodiment of the application, generally, for any application, there are often a plurality of users. In some cases, some applications allow a user to set the data processing mode of a specific service. However, statistics show that for various reasons, only a part of users often set the data processing mode of a specific service (such as a payment service, a download service, a search service, and the like), and the rest of users do not set the data processing mode. Therefore, there may be a part of users (i.e., first users) with data processing methods of specific services set therein and another part of users (i.e., second users) without data processing methods of specific services set therein.
In this embodiment, the specific service data of the first user group may include all service data of the first user group for the specific service. In another embodiment of the present application, the specific service data of the first user group may also include specific service data within a specified time range of the first user group. In an exemplary payment application scenario of the embodiment of the application, the specific service data of the first user group may include, for example, historical payment data within a specified time range of the first user group.
In the embodiment of the present application, the candidate variable set may generally include a plurality of candidate variables. Each candidate variable constitutes a user preference evaluation index or an evaluation dimension which affects the first user group. Therefore, theoretically, the more variables to be selected, the more comprehensive the consideration is, and the more realistic the user preference of the first user group can be reflected. In an exemplary payment application scenario of the present application, the set of variables to be selected may include, for example, a payment channel, a payment scenario, a payment time, a payment amount, and the like. Wherein the channel payment may include: wireless payment, PC payment, agreement payment, etc. The payment scenario may include, for example: paying in the same place, deducting money in batches, repaying house loan, repaying credit card, etc.
In the embodiment of the present application, the variable value of the candidate variable set is the variable value corresponding to each candidate variable, for example, if the service occurrence time of a specific service is taken as a candidate variable, the variable value corresponding to the candidate variable set may be 2016.11.06/12:05:53, 2016.11.10/18:15:24, 2016.11.21/09:20:03, and the like.
Of course, in the embodiment of the present application, for different applications or different services in the same application, the set of variables to be selected is generally different due to different services.
In an exemplary third party payment platform-based payment application scenario of the present application, the set of candidate variables may include a last payment time, a payment frequency, a payment amount, and the like of the first user group. Thus, the variables to be selected and the corresponding variable values thereof can be obtained as shown in the following table 1:
TABLE 1
The above table 1 lists only the candidate variable sets and their variable values of one first user in the first user group by way of example. The variables to be selected contained in the variable sets to be selected of other first users in the first user group are the same as the variables to be selected, and only the corresponding variable values are different.
And S102, determining a representative variable and a weight thereof according to the variable set to be selected and the variable value thereof, and determining a prediction model according to the representative variable and the weight thereof.
In the embodiment of the application, the influence degree value of each variable to be selected in the set of variables to be selected on the specified target variable can be determined based on a preset variable selection method; then, the specified number of variables to be selected with the maximum influence degree values are used as representative variables, and the corresponding influence degree values are used as the weights of the representative variables. And selecting a part of representative variables from the candidate variable set of the first user group as representative variables. Because the representative variables are preferably selected from all the variables to be selected through the variable selection method, the preferred representative variables in the embodiment of the application can better reflect the user preference of the first user group. In addition, the embodiment of the application does not utilize the candidate variable set, and the purpose of determining the prediction model by utilizing the representative variables is to greatly reduce the calculation amount and save the system resources.
In the embodiment of the present application, the variable selection method may be an Information entropy algorithm, an Information gain algorithm, an IV (Information Value) algorithm, or the like.
In an exemplary embodiment of the present application, the variable selection method may employ an IV algorithm. Specifically, if in a classification problem, the categories of the target variables are of two types: y1, Y2. For an individual A to be predicted, judging whether A belongs to Y1 or Y2, certain information is needed, if the total amount of the information is I, and the needed information is contained in all independent variables C1, C2, C3, … and Cn, the more information is contained in one variable Ci, the greater the contribution of the variable Ci to judging whether A belongs to Y1 or Y2 is, and the greater the information value of the variable Ci is; correspondingly, the larger the IV of Ci, the more Ci should be selected as a representative variable. The calculation formula of IV is as follows:
wherein,
from the above formula, it can be seen that IV is equivalent to woeiA weighted sum of the values, woeiThe magnitude of the value determines the degree of influence of the independent variable on the target variable. Wherein, woeiReflecting negative example user G under each group i of argumentsiIs aligned with sample user BiRatio of the total weight of the sample to the total weight of the sample GTUser-to-ensemble positive sample user BTDifference between the ratiosAnd (3) distinguishing.
In an embodiment of the present application, when the representative variables are selected by using an IV algorithm, the independent variables are each to-be-selected variable in the to-be-selected variable set, and the target variable may be a target variable of two categories. Which variable is used as the target variable of the two categories can be determined according to specific application scenarios. For example:
in an exemplary payment application scenario based on a third party payment platform, a user may bind multiple bank cards on an account of the third party payment platform, different bank cards may have different uses, and common bank card uses include: house credit cards, car credit cards, ETC cards, consumer credit cards, and the like. Moreover, some users do not want the card with the designated purpose to be deducted; for example, the money in the user's house loan card is just enough for the next loan, but if the user uses the in-person payment of the third party payment platform before the bank deducts the money, the money in the user's house loan card is deducted; the user does not sense which card is paid and used in the current time, and just the user does not open the account change short message notice of the house credit card, so that the user does not know all the account change short message notice, and the house credit deduction is easy to fail, and the payment is overdue.
Whereas if the user sets the payment selection order for payment (i.e. the user is the first user), for example: the bank card A- > the bank card B- > the bank card C means that the user wants to pay by the bank card A firstly, if the payment of the bank card A fails, the payment is considered for deducting the money of the bank card B, and the like. Generally, the common degree of consumption credit cards is mostly higher than that of house credit cards, and the common cards are mostly higher in the first-time processing success rate of payment (no one is willing to actively find trouble for himself). With this fact, therefore, the exemplary embodiment of the present application makes a reasonable assumption: the more frequently used bank cards by the user, the higher the success rate of the first-time processing of payment, thus combining the predicted payment card preference with the predicted success rate of the first-time processing of payment. Specifically, one bank card with the highest selection priority set by the first user in the payment selection order may be set as a frequently-used card (denoted as 1), and the remaining bank cards set by the first user in the payment selection order may be set as non-frequently-used cards (denoted as 0), so that the frequently-used card 1 and the non-frequently-used card 0 may be used as a target variable of the second classification.
In the scenario of selecting the representative variables based on the IV algorithm, the IV algorithm may obtain an IV value of each candidate variable, and the IV values may be sorted according to size (for example, as shown in table 2 below), so as to select a plurality of candidate variables with the largest IV values as the representative variables. In the exemplary embodiment of the application, how many variables to be selected with the largest IV value are specifically selected as representative variables can be determined through an effect test.

In the exemplary embodiment of the present application, after the representative variables are determined, the IV value corresponding to each representative variable may be determined as the weight of the representative variable, so that the prediction model may be determined according to the representative variables and the representative variables. For example, as shown in table 2 above, if V1, V2, and V3 are selected as representative variables, the determined predictive model can be expressed as a weighted sum of the variable values of the respective representative variables, as shown in the following equation:
F=1.59V1+1.52V2+1.48V2。
s103, obtaining variable values of the representative variables of each second user, and determining a data processing mode of each second user for the specific service according to the prediction model and the variable values of the representative variables of each second user; the second user comprises a user who does not set the data processing mode of the specific service.
In an embodiment of the application, after the prediction model is obtained, prediction can be performed according to the prediction model and by combining with a user environment of a second user which is not provided with a data processing mode of a specific service. The user environment of the second user, for which the data processing mode of the specific service is not set, may specify a variable value of the representative variable in a time range. Wherein the representative variables correspond to representative variables in the predictive model.
In this embodiment of the application, the data processing manner of the second user for the specific service may include, for example: a selection prioritization of particular data objects of the second user. Correspondingly, the determining, according to the prediction model and the variable value of the representative variable of each second user, the data processing manner of each second user for the specific service may be: substituting variable values of representative variables corresponding to each specific data object of a second user into the prediction model to obtain predicted values of the specific data object, and then sequencing the predicted values from large to small to serve as a data processing mode of the second user for the specific service; based on the similar processing mode, the data processing mode of each second user for the specific service can be predicted.
In an exemplary embodiment of the present application, if the prediction model is F ═ 1.59V1+1.52V2+1.48V2, there are three specific data objects a, b, and c for a second user X, according to the above method, the variable values of the representative variables (V1a, V2a, and V3a) corresponding to the specific data object a of the second user X can be obtained first, and then the prediction model is substituted to obtain the predicted value Fa of the specific data object a of the second user X, and similarly, the predicted value Fb of the specific data object b of the second user X and the predicted value Fc of the specific data object c can be obtained. And sequencing Fa, Fb and Fc in a descending order, and assuming that the sequencing result is Fa- > Fc- > Fb, the Fa- > Fc- > Fb is the data processing mode of the second user X for the specific service.
In an exemplary embodiment of the present application, the specific data object may be, for example, a payment selection sequence of each bank card bound to an account of a third party payment platform by the second user.
In an embodiment of the present application, after determining the representative variables and their weights according to the set of variables to be selected and their variable values, the method may further include:
and according to a normalization function with the slope decreasing exponentially, normalizing the variable values of the variable set to be selected to obtain the normalized variable values of the variable set to be selected.
Correspondingly, the determining a representative variable and a weight thereof according to the set of variables to be selected and the variable value thereof, and determining a prediction model according to the representative variable and the weight thereof may include:
determining a representative variable and a weight thereof according to the variable set to be selected and the normalized variable value, and determining a prediction model according to the representative variable and the weight thereof;
correspondingly, the obtaining the variable value of the representative variable of each second user may include:
and normalizing the variable value of the representative variable of each second user according to the normalization function to correspondingly obtain the normalized variable value of the representative variable of each second user.
In the embodiment of the application, a normalization function with an exponentially decreasing slope is selected, and the variable values of the variable set to be selected are normalized, so as to obtain information included in the variation of the variable values of similar variables such as the reaction times, the frequency and the like. For example, in a payment scenario, when the user pays for the first time, the historical frequency of payments changes from 0 to 1; when the user pays 100 th time, the historical payment frequency is changed from 99 th time to 100 th time. Although all are increased once, the payment frequency from 0 to 1 contains a larger amount of information than the payment frequency from 99 to 100. For example, the following steps are carried out: the user enters the social work from school graduation, and the debit card used in school to issue a prize money is used less frequently (becomes less frequently), but the historical cumulative use frequency is high due to long book reading time at school, and the historical use frequency is low due to new payroll cards issued by the company just being taken. Therefore, the payment of the old card is a relatively common one-time payment behavior, and the payment of the new card is a relatively special one-time payment behavior, which represents a certain transition of the life state of the user (embodied as the first payment after the user binds the card). And by adopting a normalization function with the slope in exponential decreasing, and performing normalization processing on the variable values of the variable sets to be selected, the difference can be better reflected, so that the user preference can be more accurately reflected by a subsequently obtained prediction model.
In an exemplary embodiment of the present application, the normalization Function with the exponentially decreasing slope may be, for example, a Logit Function, which is expressed by the following formula:
in an embodiment of the application, after the determining of the data processing manner of each second user for the specific service, the data processing manner of each second user for the specific service may be further updated periodically, so that the data processing manner of the user may adapt to the change of the user preference.
In the embodiment of the application, the variable set to be selected can be determined according to the specific service data of the first user provided with the data processing mode of the specific service; then selecting representative variables from the variable set to be selected, and determining a prediction model by the representative variables; and then predicting the data processing mode of the second user according to the prediction model and by combining the representative variable of the second user which is not provided with the data processing mode of the specific service. The prediction model learns the user preference of the first user, and statistics show that the first-time processing success rate and the processing efficiency of data processing of the first user are very high; therefore, when data processing is subsequently performed on the specific service of the second user based on the prediction model and in combination with the user environment of the second user, the first-time processing success rate and the processing efficiency of the data processing can be improved.
Referring to fig. 2, a data processing method according to an embodiment of the present application includes the following steps:
s201, receiving a data task to be processed of a specific service.
In the embodiment of the present application, the specific service may be any service of an application, such as a payment service, a download service, or a search service.
S202, when the user corresponding to the data task to be processed is a second user, matching a corresponding data processing mode from a preset data processing mode set according to the user identification of the user.
In the embodiment of the present application, the data processing method set is obtained in advance through the following steps:
determining a variable set to be selected and variable values thereof according to specific service data of a first user group; the first user group comprises a user group provided with a data processing mode of a specific service;
determining a representative variable and a weight thereof according to the variable set to be selected and the variable value thereof, and determining a prediction model according to the representative variable and the weight thereof;
obtaining a variable value of a representative variable of each second user, and determining a data processing mode of each second user for the specific service according to the prediction model and the variable value of the representative variable of each second user; the second user comprises a user who does not set the data processing mode of the specific service.
For the details of the corresponding relationship set, reference may be made to the method embodiment shown in fig. 1, which is not described herein again.
In an embodiment of the present application, in order to facilitate fast processing of data tasks, after predicting the data processing manner of each second user, the predicted data processing manners may form an ordered data processing manner set according to a corresponding relationship between the user identifier of the second user and the data processing manner thereof, for example, as shown in table 3 below:
TABLE 3
User ID |
Data processing mode ID |
Data processing mode |
0001 |
001 |
A1->A2->A3 |
0002 |
002 |
B2->B4->B3->B1 |
0003 |
003 |
C2->C1 |
In the embodiment of the application, whether the user is the first user or the second user can be determined in advance through a marking mode of the user ID. Therefore, when the data task to be processed of the specific service is received, the user type corresponding to the data task to be processed can be determined according to the user ID of the user corresponding to the data task to be processed. When the user corresponding to the data task to be processed is the second user, executing step S202; when the user corresponding to the data task to be processed is the first user, the data task to be processed can be processed directly according to the data processing mode which is set by the first user and aims at the specific service.
While the process flows described above include operations that occur in a particular order, it should be appreciated that the processes may include more or less operations that are performed sequentially or in parallel (e.g., using parallel processors or a multi-threaded environment).
Referring to fig. 3, a data processing system according to an embodiment of the present application includes:
the variable acquiring module 31 may be configured to determine a set of variables to be selected and variable values thereof according to specific service data of a first user group; the first user group comprises a user group provided with a data processing mode of a specific service;
the model obtaining module 32 may be configured to determine a representative variable and a weight thereof according to the set of variables to be selected and the variable value thereof, and determine a prediction model according to the representative variable and the weight thereof;

The data processing system of the embodiment of the present application corresponds to the method of the embodiment of the method shown in fig. 1, and therefore, specific details regarding the data processing system of the embodiment of the present application may refer to the embodiment of the method shown in fig. 1, which is not described herein again.

The prediction model learns the user preference of the first user, and statistics show that the first-time processing success rate and the processing efficiency of data processing of the first user are very high; therefore, when data processing is subsequently performed on the specific service of the second user based on the prediction model and in combination with the user environment of the second user, the first-time processing success rate and the processing efficiency of the data processing can be improved.
Referring to fig. 4, the data processing system according to the embodiment of the present invention may include a processor, an internal bus, a memory, and the like in a hardware level, and may also include hardware required by other services. The processor reads a corresponding computer program from the memory into the memory and then runs the computer program, thereby forming the data processing device on a logic level. Of course, besides the software implementation, the embodiments of the present application do not exclude other implementations, such as logic devices or a combination of software and hardware, and the like, that is, the execution main bodies of the following processing flows are not limited to each logic unit, and may also be hardware or logic devices. The memory is used for storing the data processing device; when the data processing device is processed by the processor, the following steps are executed:

The data processing system of the embodiment of the present application corresponds to the method of the embodiment of the method shown in fig. 2, and therefore, specific details regarding the data processing system of the embodiment of the present application may refer to the embodiment of the method shown in fig. 2, which is not described herein again.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functionality of the units may be implemented in one or more software and/or hardware when implementing the present application.
