Towards More Accurate Diffusion Model Acceleration with A Timestep Tuner

CVPR 2024poster

A diffusion model which is formulated to produce an image using thousands of denoising steps usually suffers from a slow inference speed. Existing acceleration algorithms simplify the sampling by skipping most steps yet exhibit considerable performance degradation. By viewing the generation of diffu…
