Reply to comment by picardythird in [D] What kind of mental framework/thought process the researchers have when working on solving/proving the math of the new algorithms? by aviisu

Stable diffusion actual implementation doesen't make sense when compared with the paper's description

Can you provide an example?

Personally, I went through Ho et al. (2020)'s paper (equation by equation) and their code (line by line) back when it first came out and I remember that they both matched each other almost perfectly.

Do you have specific examples?

It's obviously true that diffusion models don't work for the reasons they were originally thought to; the cold diffusion paper shows this. Also, Stable Diffusion explainers I've seen explain it using pixel diffusion even though it's latent diffusion. And I'm not sure I understand why latent diffusion works.
