I'm trying Building user-based recommendation model for Amazon project in Machine learning course. But I don't understand what the model needs to predict. Is it the ratings for the non rated movies? If yes, based on what data are awe expected to do that? Based on user rating for another movie? But the movies can be totally unrelated, no features such as genre have been provided. Could someone please provide some more clarity on what is expected. Thankyou!
