Alleviating Exposure Bias in Diffusion Models through Sampling with Shifted Time Steps

ICLR 2024poster

Diffusion Probabilistic Models (DPM) have shown remarkable efficacy in the synthesis of high-quality images. However, their inference process characteristically requires numerous, potentially hundreds, of iterative steps, which could exaggerate the problem of exposure bias due to the training and in…
