Learning to Rank Challenge a Success

Last year, oct. --> competition : Learning to Rank Challenge a Success | Yahoo! Labs

The goal was for participants to learn a ranking function based on the relevance judgments that were available for a training set. They had to predict the ranking of several URLs for each query in a validation set and in a test set. There were two tracks in the challenge: a standard learning to rank track and a transfer learning track where the goal was to learn a ranking function for a small market by leveraging the larger training set of another market.

It would be nice that if we could have chance to try.

It's also good to see that Yandex won the 3rd on both of two track. Although just by phone, Dmitry is a very nice person.
