Explore the similarities and differences in people's tastes in movies based on how they rate different movies. Can understanding these ratings contribute to a movie recommendation system for users? Let's dig into the data and see.
Hi, I'm working on clustering in recommender systems and in your code I want to know, if I want to cluster all movies(not 1000movies that you considered), what should I do? Is it possible or accuracy will be low because of the sparsity of this matrix? Do you know how can I cluster all movies by k-means according to their ratings
