What is backpropagation and what is it actually doing? | Deep learning, chapter 3

What's actually happening to a neural network as it learns?

Crowdflower does some cool work and addresses a meaningful need in machine learning, so I was pretty excited that they agreed to sponsor this video.

Backpropagation calculus | Appendix to deep learning part 3

This one is a bit more symbol heavy, and that's actually the point. The goal here is to represent in somewhat more formal terms the intuition for how backpropagation works in part 3 of the series, hopefully providing some connection between that video and other texts/code that you come across later.
