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.

0:23 - Recap
3:07 - Intuitive walkthrough example
9:33 - Stochastic gradient descent
12:28 - Final words
