Netflix Progress Prize for 2008 宣布了

Netflix Prize 官方網站在12月10日宣布，今年（2008）的年度成就獎頒給 BellKor in BigChaos.

It is our great honor to announce the winner of the Netflix Progress Prize for 2008 as team BellKor in BigChaos for their verified just-in-time submission on Sept 30 at 21:17:40 UTC achieving a 9.44% improvement over Cinematch. We congratulate the team of Yehuda Koren, Robert Bell and Chris Volinsky of AT&T Research Labs combined with Andreas Töscher and Michael Jahrer of Commendo Research for their superb work integrating many significant techniques to achieve this result.

In accord with the Rules the team has prepared a system description consisting of two papers, which we both make public below. We will be awarding the Prize in a presentation at the Netflix offices in Los Gatos on December 17, 2008 at 4pm. Andreas Töscher and Michael Jahrer will present a public talk at that time about their Prize algorithm. We will post a video of that presentation via the Forum.
