March 21, 2008: An update on our progress in the Netflix Prize.


Team BellKor/KorBell - Netflix Progress Prize Winners



The Netflix Progress Prize has been awarded to Team BellKor/KorBell for improving the Netflix recommendation system by 8.43%.  Team members Chris Volinsky Yehuda Koren, and  Bob Bell are with AT&T Labs Research in the Statistics and Information Visualization departments.

Check out their current performance on the Netflix leaderboard, and watch this AT&T Tech Channel interview with researchers Bob Bell and Chris Volinsky.

With the best score at the one year anniversary of the competition, they won the coveted Progress Prize. Netflix sent a cool commemorative plaque, although at a square meter in size, and weighing almost 200 pounds it is more like a monument!

Thank You We would like to thank Netflix for putting on a heck of a competition. The nature of the competition and especially the collaborative spirit of the participants has made this an exciting and rewarding scientific endeavor. We also would like to thank all of our competitors on the leaderboard for pushing us harder and forcing us to come up with the best possible solution. We look forward to chasing the million bucks with you all!
