Pseudo Numerical Methods for Diffusion Models on Manifolds
Luping Liu, Yi Ren, Zhijie Lin, Zhou Zhao

This work is a simple, effective and general high-order method for the acceleration of the diffusion model.
This work is used as the default acceleration sampling method for famous CompVis/stable-diffusion . This work is also included in other famous diffusion model open-source projects, such as huggingface/diffusers and MoonInTheRiver/DiffSinger . In addition, this work is reported by PaperWeekly.
