This is a small introduction to denoising diffusion and score-based generative models. It is based on a collection of the following resources:
Resources:
-
Diffusion-Denoising Models For a very good introduction into diffusion models you can check out the blog post from Lilian Weng: https://lilianweng.github.io/posts/2021-07-11-diffusion-models/
-
Score-Based Generative Models A good introduction is given by Yang Song here: https://yang-song.net/blog/2021/score/, https://www.youtube.com/watch?v=wMmqCMwuM2Q
