Notes

Sometimes you'd like to write your own algorithm. You can get far with rapid proptyping in numpy but a common downside is the lack of a differentiation tool. Jax is a tool that birdges this caveat. It is numpy compatible and does not force you to write code in a different way. It can even compile for use on a CPU/GPU.

Note that if you want to run jax you have to install it first. You can do that from jupyter via;

%pip install jax

This is the code that we ran in this video;

from jax import grad

def f(x):
    return x**2

grad_f = grad(f)

f(3.), grad_f(3.)
