A new research paper demonstrates that Langevin dynamics is not robust to small errors in score function estimation, unlike diffusion models. Even with arbitrarily small L2 errors, Langevin dynamics can produce distributions significantly different from the target distribution. This finding suggests that diffusion models may be more suitable than Langevin dynamics when learning score functions from data, highlighting a practical limitation of Langevin dynamics in machine learning applications.
