We'll learn about gradient descent, a technique for training neural networks. We'll then implement gradient descent from scratch in Python, so you can understand how it works. We'll implement gradient descent by training a linear regression model to predict the weather. In future videos, we'll build on this to create complex neural networks!

You can see a full explanation and code here - https://github.com/VikParuchuri/nnet_... .
