Abstract

In order to solve the problem of strong popularity bias in recommendation lists generated by Bayesian personalized ranking(BPR) algorithm under the condition of unbalanced data, this paper designed a hybrid recommendation algorithm based on feature embedding to remove popularity bias. Firstly, this paper used convolutional neural network to extract user and item features to determine user preferences, and filled the original unbalanced data according to user preferences. Secondly, it embedded the user preference features extracted from convolutional neural network into the BPR algorithm for hybrid recommendation. Finally, it trained the mixed recommendation model with score filled data, and obtained the personalized ranking list without popularity bias. In order to verify the performance of the algorithm, this paper conducted the analysis and comparison experiments on MovieLens-100K and MovieLens-1M. Experimental results show that the popularity bias is reduced by about 50%~60% and the accuracy is improved by about twice.
