Understand Neural Network Training with Micrograd

TLDRLearn how to train neural networks using the micrograd library, which implements automatic gradient calculation. Micrograd allows you to build mathematical expressions and efficiently evaluate the gradient of a loss function with respect to the network weights. By iteratively tuning the weights to minimize the loss, you can improve the network's accuracy. Micrograd is a scalar-valued autograd engine that breaks down neural networks into individual scalars, providing a fundamental understanding of backpropagation and chain rule concepts. The library consists of the engine and a small neural network library built on top of it.
