Example-based sampling with diffusion models

WebFor some diffusion models ~200 iterations is enough. So diffusion models have the benefit of an efficient training method like AR, and are much quicker to sample compared to AR. The day someone figures out a way to do one-shot or few-shot sampling of a diffusion model is the day GANs will be replaced entirely. Webconditional models, fixing those noise maps while changing the text prompt, modifies semantics while retaining structure. We illustrate how this property enables text-based editing of real images via the diverse DDPM sampling scheme (in contrast to the popular non-diverse DDIM inversion). We also show how it can be used within existing diffusion …
