How to Implement Neural Networks From Scratch With NumPy

I was reading one of the blog posts and I didn't see a clear explanation on one of the problems we were still learning. So I thought maybe I can write it and just add some information on the top of it. And yeah, my medium blog is mostly right now about deep learning to explain some of the topics that might be hard like loss functions, optimizers, normalization. You have a couple of walkthroughs on how to implement neural networks from scratch with NumPy,. which that's a fun exercise.
