Diffusion probabilistic models (DPMs) are a new class of generative models that have achieved state-of-the-art generation quality in various domains. Despite the promise, one major drawback of DPMs is the slow generation speed due to the large number of neural network eva...
Diffusion probabilistic models (DPMs) (Ho et al., 2020) have recently received growing attention due to their powerful representation learning ability and effectiveness in modeling complex data distributions. We utilize the features extracted from the dental model as the condition guiding the diffusion ...
{daquanzhou, jshfeng}@bytedance.com, xinchao@nus.edu.sg Abstract Despite the recent visually-pleasing results achieved, the massive computational cost has been a long-standing flaw for diffusion probabilistic models (DPMs), which, in turn, greatly limits their applications on resource-limited plat...

Diffusion probabilistic models (DPMs) have achieved impressive success in high-resolution image synthesis, especially in recent large-scale text-to-image generation applications. An essential technique for improving the sample quality of DPMs is guided sampling, which usually needs a large guidance scale...
Diffusion probabilistic models (DPMs) have emerged as a promising technique in generative modeling. The success of DPMs relies on two ingredients: time reversal of diffusion processes and score matching. Most existing works implicitly assume that score matching is close to perfect, while this ...
