Yahoo Labs KKD Cup
In the tradition of the Netflixprice Yahoo Labs announced the KDD Cup. Participants can compete in two tracks, one for predicting ratings, the other for separating loved from unloved songs. The competition is open to both academia and industry. Registration opens on 3/1/2011.
As a side note, with the first price being US$5,000 in the form of a check, winners outside the US will have a very hard time cashing this somewhat symbolic price. Or do you know a bank in - say - Germany that cashes US checks?
