Abstract

The present disclosure relates to a video recommendation method and apparatus. The method includes: according to the user behavior data of the target user, determining the initial user feature vector corresponding to the target user, and determining the positive sample video and negative sample video corresponding to the target user; obtaining the first optimized user feature vector corresponding to the target user through a neural network , the optimized video feature vector corresponding to the positive sample video and the optimized video feature vector corresponding to the negative sample video; according to the correlation between the optimized video feature vector corresponding to the positive sample video and the first optimized user feature vector, and the corresponding negative sample video The correlation between the video feature vector and the first optimized user feature vector is optimized, and the parameters of the neural network are optimized; based on the optimized neural network, video recommendation is performed to the target user. The present disclosure can improve the accuracy of video recommendation.

Description

technical field [0001] The present disclosure relates to the field of video technologies, and in particular, to a video recommendation method and device. Background technique [0002] Because the information of online videos is uneven and the content is complicated, the operators of video websites usually choose the recommendation algorithm based on collaborative filtering to recommend videos. In recent years, with the rapid development of the Internet industry and multimedia technology, the amount of online video and video users has grown rapidly. The huge amount of videos and users makes the rating matrix in collaborative filtering sparse, resulting in low video recommendation accuracy. SUMMARY OF THE INVENTION [0003] In view of this, the present disclosure proposes a video recommendation method and apparatus. [0004] According to an aspect of the present disclosure, a video recommendation method is provided, including: [0005] Determine the initial user feature v...
