直观理解反向传播（深度学习 第3章）

3Blue1Brown's third deep learning chapter gives a visual, intuitive account of backpropagation and what happens to a neural network as it learns. A follow-up video covers the underlying calculus.

Why HN likes it: Recommended as the most accessible introduction to backprop for people who struggle with the pure math.

“I found the explainations by 3Brown1Blue to be very intuitive when it comes to neural networks”
