Simple Collaborative Filtering

In: statistical

10 Oct 2009

Collaborative filtering is a way of trying to present more relevant information to users, by choosing what to show based on how other users have acted. The "You might also like" boxes on Amazon and similar are probably the most popular example of this kind of technology, but it's applicable in recommending all kind of content outside of ecommerce, particular anything that often has user ratings, such as video or games.
