It was originally developed by French physicist Paul Langevin. The approach is characterized by the use of simplified models while accounting for omitted degrees of freedom by the use of stochastic differential equations.

Teh. "Bayesian learning via stochastic gradient Langevin dynamics In computational statistics, the Metropolis-adjusted Langevin algorithm (MALA) or Langevin Monte Carlo (LMC) is a Markov chain Monte Carlo (MCMC) method for obtaining random samples – sequences of random observations – from a probability distribution for which direct sampling is difficult. Monte Carlo Sampling using Langevin Dynamics Langevin Monte Carlo is a class of Markov Chain Monte Carlo (MCMC) algorithms that generate samples from a probability distribution of interest (denoted by $\pi$) by simulating the Langevin Equation. The Langevin Equation is given by Improved configuration space sampling: Langevin dynamics with alternative mobility.

In Section 3, we construct the novel Covariance-Controlled Adaptive Langevin (CCAdL) method that can effectively dissipate parameter-dependent noise while maintaining the correct distribution. Various numerical experi- convex, discretized Langevin dynamics converge in iteration complexity near-linear in the dimension.

Markov chain Monte Carlo (MCMC) is a kind of sampling methods, which is widely used in the inference of complex probabilistic models. We show how to derive a simple integrator for the Langevin equation and illustrate how it is possible to check the accuracy of the obtained distribution on the fly, using the concept of effective energy introduced in a recent paper [J. Chem. Phys.
