The invention relates to a training method of an information recommendation model and an information recommendation method and device. The information recommendation model training method comprises the steps of obtaining initial sample features and an actual operation result of a sample account for sample recommendation information; the initial sample features are obtained according to sample account features and sample information features; inputting the initial sample features into a to-be-trained information recommendation model to obtain a prediction operation result of the sample account for the sample recommendation information; the model comprises a gating structure and a plurality of feature extraction layers, the plurality of feature extraction layers are used for outputting a plurality of target sample features, the output value of the gating structure represents the importance degree of each target sample feature, and the prediction operation result is obtained according to the plurality of target sample features and the output value of the gating structure; and based on the difference between the predicted operation result and the actual operation result, training the information recommendation model to obtain a trained information recommendation model. According to the invention, the recommendation accuracy of the trained information 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 of an information recommendation model, an information recommendation method, an apparatus, an electronic device and a storage medium. Background technique [0002] With the development of information recommendation technology, there is a technology that uses the information recommendation model for information recommendation. By training the information recommendation model, when performing information recommendation, the information features of the recommended information contained in the recommendation information database and The user characteristics of the recommended users for information recommendation, and the information characteristics and user characteristics are input into the recommendation model, and the model can output the probability of the user accessing each recommended information, so as to provide users with r...
