Back Propagation

These notes are from the video series of CampusX YouTube' playlist: 100 Days of Deep Learning. I have just written these for myself and for others to refer in future.

In this notes, we'll have a try to understand what is back propagation. You can find the first video of the series here.

Prerequisites:

• Forward propagation

• Gradient descent

• Notations: https://youtu.be/H0_3SJh4Rqs?si=G6mu8dLpMmjcVt68

Notes are divided into 2 parts:

• What is back propagation?

• How does it work?
