[2105.05233v2] Diffusion Models Beat GANs on Image …

WebDec 26, 2024 · Diffusion is an iterative process that tries to reverse a gradual noising process. In other words, in diffusion, there exists a sequence of images with increasing amounts of noise, and during training, the model is given a timestep, an image with the corresponding noise level, and some noise. The goal then is to reconstruct the input … 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. jesus wineskins
