In this talk, I will present different algorithms for the collaborative
filtering task. The task of collaborative filtering is to predict
the preferences of a user, given preferences of other users.
An example of a commercial collaborative filtering system is the movie
recommendation algorithm Netflix's Cinematch, which predicts the customer's
rating for a given movie. Recently, Netflix, the world's largest online DVD
rental service, released to the public a large database of 17770 movies,
rated by 480189 customers, and announced a $1M prize for 10% improvement
in prediction accuracy over Cinematch on the dataset.
I will give an overview of my solution - better than Cinematch by over 3%.
