inejc/painters: Winning solution for the Kaggle competition Painter by Numbers

Speaking of ensembles winning Kaggle, here's an excellent writeup by the winner of a recent Kaggle competition on his solution. The entire writeup is worth reading to walk through the author's approach, but the real payload is at the end: "The bad news is that the described algorithm is not good at extrapolating to unfamiliar artists. This is largely due to the fact that same identity verification is calculated directly from the two class distribution vectors."

So: a ton of work, a winning solution, but not broadly applicable. This stuff is hard.
