Flow Matching and Diffusion Models from Scratch: Free Lecture Notes

Lecture notes from Peter Holderrieth and Ezra Erives covering flow matching and diffusion models from scratch. No background in generative modeling assumed. Goes from the math up to current state of the art. Reading the original papers in sequence (DDPM, DDIM, flow matching) works, but each one assumes you got something from the previous. These notes don't make that assumption.
