What is backpropagation really doing? | Chapter 3, deep learning

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

Training data generation + T-shirt at http://3b1b.co/crowdflower
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.

The following video is sort of an appendix to this one. The main goal with the follow-on video is to show the connection between the visual walkthrough here, and the representation of these “nudges” in terms of partial derivatives that you will find when reading about backpropagation in other resources, like Michael Nielsen’s book or Chis Olah’s blog.

Thanks to everyone supporting on Patreon.
