Langevin dynamics sampling

25 May 2007 Accurate sampling using Langevin dynamics. Giovanni Bussi* and Michele Parrinello. Computational Science, Department of Chemistry and  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 An important basic concept in sampling is Langevin dynamics [15].

In this paper, we introduce Langevin diffusions Among them, the stochastic gradient langevin dynamics (SGLD) algorithm, introduced in [33], is a popular choice. This method is based on the Langevin Monte Carlo (LMC) algorithm proposed in [16, 17]. Standard versions of LMC require to compute the gradient of the log-posterior at the current fit of the parameter, but avoid the accept/reject step. Importance sampling.

Langevin dynamics sampling

In Bayesian machine learning, sampling methods provide the asymptotically unbiased estimation for the inference of the complex probability distributions, where Markov chain Monte Carlo (MCMC) is one of the most popular sampling methods.

In practice, this approach can be prohibitive since we still need to often query the expensive PDE solvers. The Dynamics-based sampling methods, such as Hybrid Monte Carlo (HMC) and Langevin dynamics (LD), are commonly used to sample target distributions. Re-cently, such approaches have been combined with stochastic gradient techniques to increase sampling efficiency when dealing with large datasets. An outstanding With regard to the approximation of canonical averages, methods have previously been constructed for Brownian dynamics with order >1 and for Langevin dynamics with order >2 [24, 18], but these require multiple evaluations of the force; for this reason , they are not normally viewed as competitive alternatives for molecular sampling . We establish a new convergence analysis of stochastic gradient Langevin dynamics (SGLD) for sampling from a class of distributions that can be non-log-concave. At the core of our approach is a novel conductance analysis of SGLD using an auxiliary time-reversible Markov Chain.
