Two new arXiv papers explore advanced Langevin dynamics for improved sampling in machine learning. The first paper introduces TIPreL, a novel time- and position-dependent preconditioner designed to simultaneously address global mode coverage and local mode exploration challenges in sampling from complex distributions. The second paper analyzes the kinetic Langevin Monte Carlo method with a stochastic exponential Euler discretization, refining existing analyses to show its stability and effectiveness even in the overdamped regime with appropriate time acceleration.
