Abstract

The present disclosure relates to a training method, recommendation method, device, server and storage medium of a recommendation model. The training method of the recommendation model includes: obtaining training sample data; the training sample data includes sample account features, sample information features, and the actual access results of the sample account for the sample recommendation information; inputting the sample account features and sample information features into the recommendation model to be trained , obtain the predicted access result of the sample account for the sample recommendation information; based on the predicted access result and the actual access result, determine the value of the first loss function, and, based on the actual value and expected value of the gating parameter, determine the value of the second loss function; Based on the value of the first loss function and the value of the second loss function, a total loss value is determined; based on the total loss value, the recommendation model and gating parameters are updated to obtain a trained recommendation model. The present disclosure can realize autonomous update of gating parameters, so that the flexibility of the trained recommendation model can be improved.

Description

technical field

[0001] The present disclosure relates to the technical field of information recommendation, and in particular, to a training method, recommendation method, device, server and storage medium of a recommendation model. Background technique

[0002] With the development of information recommendation technology, there is a technology that uses neural network model to achieve information recommendation. By training the recommendation model, when recommending information to users, the characteristics of the recommended information and the user's characteristics can be input into the model. , the model outputs the probability of users accessing each recommendation information, so as to provide users with recommendation information with a high degree of fit.

[0003] In the related art, in the current recommendation model, after the characteristics of the recommendation information and the characteristics of the user are obtained, the above-mentioned characteristics ...
