Progressive Distillation for Fast Sampling of Diffusion Models – Fast sampling progressive distillation can generate images in as few as 4 steps. It needs model-level training. WebJun 21, 2024 · The idea behind these models is that a diffusion process equates to a loss of information due to gradual intervention of noise (a gaussian noise is added at every timestep of the diffusion process). The goal of such a model is to learn the impact of noise on the information available in the sample, or in other words how much the diffusion ... today iowa state vs clemson 2021
