“The secret of the big guys” (from FastML)

FastML has an intriguing post called The secret of the big guys, which starts thus:

Are you interested in linear models, or K-means clustering? Probably not much. These are very basic techniques with fancier alternatives. But here’s the bomb: when you combine those two methods, you can get better results than from a random forest. And maybe even faster.

It definitely sounds worth trying, and there are links to some papers with Andrew Ng as a co-author in the blog post. I haven’t had time to try out Sofia-ML yet, or to implement this approach by hand, but I’ll definitely give it a shot at some distant point in time when I don’t have my hands full.
