On the Convergence of the Unadjusted Langevin Algorithm
20.7 parsecs away

Travel
| The Langevin algorithm is a simple and powerful method to sample from a probability distribution. It's a key ingredient of some machine learning methods such as diffusion models and differentially private learning. In this post, I'll derive a simple convergence analysis of this method in the special case when the ...
