Backpropagation Details Pt. 2: Going bonkers with The Chain Rule

This StatQuest picks up right here Part 1 left off, and this time we're going to go totally bonkers with The Chain Rule and optimize every single parameter in this simple Neural Network. BAM!!!

NOTE: This StatQuest assumes that you already know the main ideas behind Backpropagation: Neural Networks Pt. 2: Backpropagatio...
...and that also means you should be familiar with...
Neural Networks: The Essential Main Ideas of Neural Ne...
The Chain Rule: The Chain Rule
Gradient Descent: Gradient Descent, Step-by-Step

LAST NOTE: When I was researching this 'Quest, I found this page by Sebastian Raschka to be helpful: https://sebastianraschka.com/faq/docs...
