Netflix Competition

Netflix prize is a competition on predicting customers' movie ratings. We are given a #movies x #customers matrix. Each entry corresponds to a customer's rating to a particular movie. Only some entries of this matrix are available, and they are referred to as training data. We then construct a model to predict those missing entries.

This is an ongoing competition. We hope to submit some results in the end of this course.
