BellKor's Pragmatic Chaos 在他們的網頁上宣佈,他們已經達到 10.05% 的成果,所以他們贏得本次大獎賽。
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.
此刻 Netflix Prize Leaderboard 也顯示 BPC 在 2009-06-26 18:42:37 提出的成果已經達到 10% 門檻值:
Update 1:
RWW 隨後也報導了這個消息, Marshall Kirkpatrick 執筆的 They Did It! One Team Reports Success in the $1m Netflix Prize 文中簡述比賽的背景,並且引用紐約時報的專文 If You Liked This, You’re Sure to Love That 談到所謂正確預測用戶的喜好,不見得是萬靈丹。下一代的推薦系統,還有很長的路要走。
Update 2:
真正的推薦系統行家人Greg Linden 顯然知道更多內情,他不僅說明 BPC 是由四個團隊合併合成,還提醒大家一件事,別的團隊有一個月的緩衝時間逆轉局勢:Other teams have 30 days to beat it, but, no matter what happens, the $1M prize will be claimed in the next month。
不論最後結局如何,恭喜得勝的團隊,Congratulations to the winners!
