Neural denoising diffusion models

Denoising diffusion probabilistic models (DDPMs), score-based generative models, generative diffusion processes, neural energy models…



Placeholder.

AFAICS, generative models using score-matching to learn and Langevin MCMC to sample. There are various tricks needed to to do it with successive denoising steps and interpretation in terms of diffusion SDEs. I am vaguely aware that this oversimplifies a rich and interesting history of convergence of many useful techniques, but have not invested enough time to claim actual expertise.

Training: score matching

Denoising score matching HyvΓ€rinen (2005). See score matching or McAllester (2023) for an introduction to the general idea.

Sampling: Langevin dynamics

See Langevin samplers.

Image generation in particular

See image generation with diffusion.
