Elucidating the Exposure Bias in Diffusion Models

4 code implementations29 Aug 2023 Mang Ning, Mingxiao Li, Jianlin Su, Albert Ali Salah, Itir Onal Ertugrul

In this paper, we systematically investigate the exposure bias problem in diffusion models by first analytically modelling the sampling distribution, based on which we then attribute the prediction error at each sampling step as the root cause of the exposure bias issue.

Input Perturbation Reduces Exposure Bias in Diffusion Models

1 code implementation27 Jan 2023 Mang Ning, Enver Sangineto, Angelo Porrello, Simone Calderara, Rita Cucchiara

Denoising Diffusion Probabilistic Models have shown an impressive generation quality, although their long sampling chain leads to high computational costs.
