Slowly Annealed Langevin Dynamics: Theory and Applications to Training-Free Guided Generation
Slowly Annealed Langevin Dynamics (SALD) and its extension, Velocity-Aware SALD (VA-SALD), offer a method for training-free guided image generation. VA-SALD tracks moving target distributions by slowing down the sampling process to focus correction only on deviations caused by the guide, achieving stable results without needing full path complexity.
