Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It should be noted that the embodiments of the present invention and the technical features of the embodiments may be combined with each other without conflict.
Fig. 1 is a schematic diagram of main steps of a method for displaying article information according to an embodiment of the invention.
As shown in fig. 1, a method for displaying article information according to an embodiment of the present invention mainly includes the following steps:
step S101: acquiring user information, and determining a user portrait corresponding to the user information; wherein the user representation is derived based on user attributes corresponding to the user information and/or historical behavior data of the user.
The user information can be registration information or login information of the user, and before the user information is acquired, a user portrait can be constructed in advance according to user attributes and historical behavior data of the user. The user attributes can include population attributes, social attributes, family information, property information, user preference information, whether the user is a member or not and the like, the population attributes include gender, age, geographical position where the user is located and the like, the social attributes include marital status, occupation and the like, the family information includes the number of children and the age and the like, and the property information includes whether the vehicle exists or not and the like. The historical behavior data of the user comprises historical behaviors of clicking, browsing, paying attention, collecting, shopping cart adding, ordering and the like of the user history.
In order to improve the accuracy of constructing the user portrait, the user portrait may be constructed according to multi-dimensional user behavior data, for example, the user portrait may be constructed by using user behavior data of the user in different time periods, such as constructing the user portrait by combining real-time behavior data (behavior data of the user within 5min from the current time), short-term historical behavior data (behavior data of the user within 15 days from the current time), medium-term historical behavior data (behavior data of the user within 3 months from the current time), and long-term historical behavior data (behavior data of the user within 1 year from the current time), so that the constructed user portrait is more accurate.
Step S102: and determining an article to be displayed according to the user portrait.
When an article to be displayed corresponding to the user portrait is determined, the user portrait can be used as the input of an article prediction model, and the article to be displayed is determined according to the output of the article prediction model; the item prediction model is obtained based on the user attributes, the historical behavior data of the user and the items corresponding to the historical behavior data of the user.
Wherein the goods prediction model is generated based on the GBDT-CNN-DNN model, and the main architecture of the GBDT-CNN-DNN model can be as shown in FIG. 2. When training the article prediction model, the input features may be user attributes, historical behavior data of the user, and article information corresponding to the historical behavior data of the user. During model training, user attributes, historical behavior data of a user and sample data related to the historical behavior data of the user can be input into a model, low-order features are extracted through a Linear Part of a GBDT-CNN-DNN model, high-order features are extracted through a CNN Part and a DNN Part, the low-order features and the high-order features are spliced before entering an input layer, the spliced features are input into the input layer of the GBDT-CNN-DNN model, and then the features can be converted into mathematical vectors by the input layer so as to facilitate model training. In the model training process, the exponential weighting moving average is carried out on the sample data on the basis of the random gradient so as to carry out deviation correction on the momentum in a time step, and the learning rate of each element in the model parameters is readjusted through operation according to the elements, so that each element in the objective function independent variable has the learning rate of the element, the model is converged stably and quickly, and the model training efficiency is improved.
In addition, focal-loss is added into the loss function of the GBDT-CNN-DNN model, and the loss function of the goods prediction model is improved into a function shown in formula (1):
Lossfocal＝-αy2(1-y)γlogy………………(1)
wherein y represents the predicted probability value of the model, namely the result output by softmax of the GBDT-CNN-DNN model, and alpha and gamma are the modulation coefficients of focoal-loss. The modulation coefficient makes the GBDT-CNN-DNN model more focused on samples which are difficult to classify during training by reducing the weight of samples which are easy to classify. Alpha is used to balance the number of samples, and gamma is used to control the mining of samples that are difficult to classify, corresponding to a penalty term. When γ is 1, the cross entropy loss is obtained, and when γ is increased, the loss of samples which are easy to classify is reduced, and the loss of samples which are difficult to classify is relatively large.
In the prior art, during model training, activating functions such as Relu and Sigmoid are usually selected, and the division points of the activating functions are all 0, so that the model prediction accuracy is limited by adopting a fixed division point mode. In the embodiment of the invention, the activation function is improved, so that the segmentation point is determined by the data per se, and the model prediction accuracy is improved. Specifically, the improved activation function is shown in equation (2):
wherein m isiCharacterizing the predictive data, piCharacterizing the prediction probability, aiAnd characterizing preset parameters. Therefore, through the improved multi-classification self-adaptive nonlinear mapping, the segmentation points are adjusted according to the expectation and the variance of the data in MiniBatch, and compared with the method that Relu, sigmoid and the like adopt fixed segmentation points 0, the characteristics of the data set can be learned, so that the recall rate of the model in the verification set is improved, and the prediction accuracy rate of the model is further improved.
After the article prediction model is trained and before the article prediction model is brought online, the article prediction model needs to be tested, for example, when an article to be displayed corresponding to a user portrait is determined through a server and article information of the article to be displayed is displayed through a user terminal, joint debugging can be performed on the terminal and the server, and multi-angle testing can be performed on the effect of the model through a regression centralized example, so that the stable performance and the reliable effect of the article prediction model in the application process are ensured.
In addition, similar to the construction of the user image, the article prediction model may be trained according to multidimensional user behavior data, for example, the article prediction model may be trained by using user behavior data of the user in different time periods, for example, the article prediction model may be trained by combining real-time behavior data (behavior data of the user within 5min from the current time), short-term historical behavior data (behavior data of the user within 15 days from the current time), medium-term historical behavior data (behavior data of the user within 3 months from the current time), and long-term historical behavior data (behavior data of the user within 1 year from the current time), so that the trained article prediction model is more accurate.
Further, the output of the item prediction model includes: item information of a plurality of items and item information of the plurality of items respectively correspond to matching degrees of the user images; the determining the item to be displayed according to the output of the item prediction model comprises: and determining the article corresponding to the article information with the matching degree larger than the threshold value as the article to be displayed. Thus, the item information that matches the user figure best can be selected based on the score (matching degree) of each item information output by the item prediction model, thereby providing more accurate item recommendation to the user.
That is, the trained item prediction model may be used to determine the item information corresponding to the user image, and as shown in fig. 3, the item information display method according to the embodiment of the present invention may include the following steps S301 to S303:
step S301: user information is obtained and a user representation corresponding to the user information is determined.
Wherein the user representation is derived based on user attributes corresponding to the user information and/or historical behavior data of the user.
Step S302: and taking the user image as an input of an article prediction model to obtain article information of a plurality of articles output by the article prediction model and matching degrees of the article information of the plurality of articles corresponding to the user image respectively.
The item prediction model is obtained based on the user attributes, the historical behavior data of the user and the items corresponding to the historical behavior data of the user.
Step S303: and determining the article corresponding to the article information with the matching degree larger than the threshold value as the article to be displayed, and displaying the article information of the determined article to be displayed on the page currently viewed by the user.
