Abstract

The embodiment of the invention provides a recommendation model training method and device, a medium and computing equipment. The method comprises the steps of generating a training sample based on a push record of push content and an interactive operation record of a user on the push content, the training sample comprising popularity corresponding to the push content and a label value indicating whether the user has an interactive operation on each push content; the training samples are input into a recommendation model for training, the user feature parameters and the content feature parameters are output, and the recommendation model is a matrix decomposition model. The popularity is brought into a training target, so that popular and non-popular factors in the obtained user feature parameters and content feature parameters are decoupled, the leading effect of popular contents on a recommendation model when determining to-be-pushed contents is reduced, the Mortai effect that the pushed contents are biased to popular is reduced, and the pushing quality of the to-be-pushed contents is improved. The coverage degree of interest preference fields except user popularity is improved, and better experience is brought to the user.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and more particularly, the embodiments of the present disclosure relate to a recommendation model training method, medium, apparatus, and computing device. Background technique [0002] This section is intended to provide a background or context for the embodiments of the present disclosure that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the development of Internet technology, the content recommendation function is used in more and more applications. By pushing corresponding content according to the characteristics of user traffic, the user experience can be improved. [0004] Current recommender systems prefer to recommend popular content to users. And for these popular content, because it has more exposure opportunities, it will be more popular. For content that has not been push...
