In our books recommendation system, we. To use the recommendation system for this user as well, we just need to compute the mean ratings for each movie and use this mean rating vector as a prediction. Recommender system is still a hot research topic in computing math and computer science.in 2006, netflix held a competition called netflix prize to find an efficient recommender system algorithm.
