Normalizing Flows: A Flowy Approach to Generative Modeling

Imagine you have a pile of random socks in front of you. How do you organize them to create a beautiful, paired-up spectacle?

Enter normalizing flows, the magical tool that can transform any random distribution into a standard normal distribution, allowing us to generate new data that looks like the original.

So, what exactly is a normalizing flow? It’s a bijective transformation, which means it can go both ways. It takes a distribution and bends and twists it until it looks like the standard normal distribution. And the cool part?
