Improved Denoising Diffusion Probabilistic Models

18 Feb 2021 Alex Nichol Prafulla Dhariwal

Denoising diffusion probabilistic models (DDPM) are a class of generative models which have recently been shown to produce excellent samples. We show that with a few simple modifications, DDPMs can also achieve competitive log-likelihoods while maintaining high sample quality... (read more)
