Problems solved by technology

At present, there are many video recommendation schemes that solve computationally complex problems, but the data involved often expose the user’s private information, such as user points of interest, user cities, user devices, etc. Therefore, how to enhance the efficiency of video recommendation while achieving privacy protection is a key issue. A problem that needs to be solved

Abstract

The invention discloses a short video recommendation method, system and device, and the method comprises the steps: obtaining two feature vectors of a target video, decomposing a target fusion tensor into a core tensor and three factor matrixes through Tucker, and fusing the two feature vectors of the target video with the core tensor and the three factor matrixes by using Tucker fusion, adding noise for the core tensor through differential privacy in the fusion process to obtain a fused target feature privacy vector, and then calculating a final prediction result through neural collaborative filtering. Whether to recommend the target video to the target user is judged through the final prediction result, and privacy protection, feature fusion and a recommendation system are realized on the whole.

Description

technical field [0001] The present invention relates to the technical field of video recommendation, in particular to a short video recommendation method, system and equipment. Background technique [0002] The recommendation system mainly discovers the characteristics of items that are of interest to users by contacting users and item information, and then pushes item information that users may be interested in to users, so as to achieve a win-win situation for information consumers and information producers; with the popularization of mobile terminals With the speeding up of the Internet, short videos, an Internet content dissemination method, are rapidly emerging on major platforms. How to quickly and effectively predict and push the videos that each user is interested in is a current research direction. At present, there are many video recommendation schemes that solve computationally complex problems, but the data involved often expose the user’s private information, su...
