Proposing BayesDiff for estimating pixel-wise uncertainty in diffusion models using Bayesian inference.
Аннотация
BayesDiff introduces a novel approach to estimate pixel-wise uncertainty in diffusion models. It leverages Bayesian inference to characterize uncertainty dynamics and improve image quality. The method shows promise for diverse applications, including text-to-image tasks.
