Bravo!  I should note that current "recommender" systems don't much help me make further selections.

I thank Jüri Saar for the pointer.

Wait, the winning team’s webpage says other competitors have the next month to enter in their best model.

I really hope they follow this up with another similarly themed contest.

How do they avoid curve fitting their models?

@John: I think contestants got a training data set, and predictions were then tested against subsequent, real ratings from customers (see So overfitting to the training set would not have been an advantage.
