So I submitted my first entry last night - it did poorly, of course, but at least I'm on the Leaderboard! (I'm "teamgreg" because I really didn't want to think of a name) Crunched some more numbers last night in support of my next submission, which I have to wait a week for. It's a little annoying that just reading in all 100 million entries takes, at a minimum, 40 minutes (not to mention any processing, but that's all been pretty quick so far), although it works decently if we're doing other things that I can start a run of that and then get back to something else. As long as that "something else" isn't WoW, because it really sloooows my computer down. :-)
I'm impressed one team already has a RMSE (root mean squared error) of .9571, which is within spitting distance of .9474, which is how Netflix's algorithm does on the data.
