A Neural Network in 11 lines of Python

Summary: I learn best with toy code that I can play with. This tutorial teaches backpropagation via a very simple toy example, a short python implementation.

Edit: Some folks have asked about a followup article, and I’m planning to write one. I’ll tweet it out when it’s complete at @iamtrask. Feel free to follow if you’d be interested in reading it and thanks for all the feedback!
