Neural networks

An overview of neural networks.

1. 

   1. But what is a Neural Network?

   2017-10-05

   Introduction to neural networks.

2. 

   2. Gradient descent, how neural networks learn

   2017-10-16

   The goal of this video is to introduce the idea of gradient descent and to analyze a specific network.

3. 

   3. What is backpropagation really doing?

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

4. 

   4. Backpropagation calculus

   2017-11-03

   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.
