Cache Mechanisms in Diffusion Models
How to generate high-quality images and videos faster has long been a central objective in the generative modeling community. Early explorations mainly followed a numerical-analysis perspective: researchers aimed to design more efficient ODE solvers, such as DDIM1, DPM-Solver2, and iPNDM3, to approximate the target distribution with fewer sampling steps. At the same time, distillation is also an effective acceleration approach, although it usually requires additional training and higher resource cost. ...
