Slashdot points out Google Predict. I’m not privy to the details, but this has the potential to be extremely useful, as in many applications simply having an easy mechanism to apply existing learning algorithms can be extremely helpful. This differs goalwise from MLcomp—instead of public comparisons for research purposes, it’s about private utilization of good existing algorithms. It also differs infrastructurally, since a system designed to do this is much less awkward than using Amazon’s cloud computing. The latter implies that datasets several order of magnitude larger can be handled up to limits imposed by network and storage.
