The Netflix Prize Comes To A Buzzer-Beater, Nailbiting Finish
Who knew statistical computing competitions could be so cut throat? Since we reported on the contest last night, two teams in the Netflix Prize have spent the last few hours jumping back and forth on the Netflix leaderboard as the three-year-long competition ticked into its final moments, with last minute sniping submissions coming from both sides. Finally, the results are in: The Ensemble has managed to come from behind to upset BellKor’s Pragmatic Chaos with a top submission of 10.10% — an improvement of .01% — only 4 minutes before the contest closed.
It’s been a long road to get here. Over the last three years computer science teams around the world have been vying for the Netflix Prize — a competition that invited teams to try to improve on Netflix’s movie recommendation algorithm by 10%, with a reward of $1 million to the best submission. Since then teams have gotten progressively closer to the magical 10% mark, but it wasn’t until last month when a number of top teams joined forces to form BellKor’s Pragmatic Chaos that the barrier was finally broken, with a score of 10.08%. However, their announcement kicked off a 30 day last call period where other teams were invited to make their final submissions.
