| Abstract: |
| In this work, we investigate the problem of sampling with Langevin diffusion in non-convex setting. Compared with [6], we extend the result under 2-Wassertain distance, and we find a better explicit positive constant c in the exponential convergency. |
| Key words: Langevin diffusion sampling Wasserstein distance |
