In third place is a four-person team from University of Toronto, including Prof. Geoffrey Hinton, a well known person in the machine learning community.<br /><br />Looks like the competitors approach the task really professionally. A recent article in the New York Times, <a href="http://www.nytimes.com/2007/06/04/technology/04netflix.html?ex=1338609600&en=eda04055720ce432&ei=5088&partner=rssnyt&emc=rss">"Netflix Prize Still Awaits a Movie Seer"</a>, cites the leader of Team Gravity:<br />"Domonkos Tikk, a data mining expert who is a senior researcher at the university in Budapest, leads Team Gravity. Dr. Tikk said that since October, his team, which is composed of three Ph.D. candidates and himself, has spent eight hours a day, seven days a week on the problem".<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7948448060991407843-631211891565440927?l=arekpaterek.blogspot.com' alt='' /></div>Arek Paterekhttp://www.blogger.com/profile/10024063805816504858noreply@blogger.com0tag:blogger.com,1999:blog-7948448060991407843.post-13510224694023096632007-05-22T13:30:00.000+02:002007-07-05T11:48:45.177+02:00I advanced to the top ten in the <a href="http://netflixprize.com/">Netflix Prize</a>.<br /><br />"Torture the data long enough, and sooner or later it will confess."
