Another interesting article - Back Propagation

For my CS 295 Machine Learning class, I was reading up on back propagation algorithms. This is a really good page that describes the principles really well. I'm currently implementing a back propagation algorithm which is classifying some data that my professor provided us. It's pretty interesting, and rather fun. Although using something like a blackbox ANN is kind of confusing, only because it's so very annoying to debug.
