One interesting thing in the discussion was the Netflix challenge, unfortunately they didn’t get much into it. Would a simpler method be able to solve it more efficiently?
I saw an interesting argument that weighted average of prediction by each system should be expected to win based on a property of the error metric used (root mean square error is convex).
