Data Piques Matrix Factorization in PyTorch

Hey, remember when I wrote those ungodly long posts about matrix factorization chock-full of gory math? You can forget it all. We have now entered the Era of Deep Learning, and automatic differentiation shall be our guiding light. Less facetiously, I have finally spent some time checking out these new-fangled deep learning frameworks, and damn if I am not excited. In this post, I will show you how to use PyTorch to bypass the mess of code from my old post on Explicit Matrix Factorization and instead implement a model that will converge faster in fewer lines of code.
