June 26th, 2009

BellKor’s Pragmatic Chaos has broken the 10% barrier, a feat that may have won them the $1M Netflix prize. We’ll know for sure in 30 days.

“June 26, 2009: Today our team submitted our solution to the Netflix Prize, resulting in a score of .8558, which corresponds to an improvement over Netflix Cinematch algorithm of 10.05%. This is the first submission in the competition to break the 10% barrier and sets off a 30 day period where all competitors are invited to submit their best and final solutions.

The prize is the award by Netflix for an open competition that started in October 2006 for the best collaborative filtering algorithm predicting user ratings for films from a database of previous ratings. Today the BellKor’s Pragmatic Chaos team submitted an entry that improved on the existing algorithm by 10.05%, exceeding the 10% improvement threshold required of a winner. The team is a collaboration between people from Pragmatic Theory, Commendo, Yahoo and AT&T.
