Neural networks Episodes

1. But what is a Neural Network?

October 5th, 2017

Introduction to neural networks.

2. Gradient descent, how neural networks learn

October 16th, 2017

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

3. What is backpropagation really doing?

November 3rd, 2017

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

4. Backpropagation calculus

November 3rd, 2017

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.
