Abstract:Nowadays, the problem of information overload is becoming more and more serious. In the sea of big data, it has been a huge challenge to improve the recommendation performance of moie recommendation system for different users. In order to effectively solve the problems of information overload and low user experience satisfaction, it is necessary to choose an appropriate personalized recommendation algorithm. In this paper, the mainstream machine learning recommendation algorithms are summarized, and the advantages and disadvantages of each algorithm are compared and analyzed through experiments. Finally, corresponding solutions are proposed to solve the common problems of cold start and data sparsity in recommendation algorithms.

Key words: film recommendation, collaborative filtering(CF), cold start, singular value decomposition(SVD)
