The Langevin Dynamics (LD) methodology consists of essentially applying Newton's II law to model the motion of a suspended particle that is much heavier than the molecules of the background gas (Mazur & Oppenheim, 1970), while including the systematic resistance to particle motion exerted by the gas medium (in the R e p → 0, M a p → 0 limit) as a time-averaged continuum drag force F → D and the random thermal impulses exerted by the gas molecules on a particle through discrete impacts Stochastic Gradient Langevin Dynamics. The authors of the Bayesian Learning via Stochastic Gradient Langevin Dynamics paper show that we can interpret the optimization trajectory of SGD as a Markov chain with an equilibrium distribution over the posterior over \(\theta\).

The naïve approach of incorporating Brownian motion into the mirror descent dynamics, which we refer to as Symmetric Mirrored Langevin Dynamics (S-MLD), is shown to connected to the theory of Weighted Hessian Manifolds. 2.2. Langevin Diffusions Langevin dynamics is a common method to model molecular dynamics systems.

Stochastic Gradient Langevin Dynamics Given the similarities between stochastic gradient al-gorithms (1) and Langevin dynamics (3), it is nat-ural to consider combining ideas from the two ap-proaches.
The algorithm performs stochastic gradient descent, where in each step it injects appropriately scaled Gaussian noise to the update. We analyze the algorithm’s hitting time to an arbitrary sub-set of the parameter space. Mirrored Langevin Dynamics. 02/27/2018 ∙ by Ya-Ping Hsieh, et al. ∙ EPFL ∙ 0 ∙ share . We generalize the Langevin Dynamics through the mirror descent framework for first-order sampling.

3. Stochastic Gradient Langevin Dynamics Given the similarities between stochastic gradient al-gorithms (1) and Langevin dynamics (3), it is nat-ural to consider combining ideas from the two ap-proaches. This allows eﬃcient use of large datasets while allowing for parameter uncertainty to be cap-tured in a Bayesian manner. The approach is Stochastic gradient Langevin dynamics (SGLD), is an optimization technique composed of characteristics from Stochastic gradient descent, a Robbins–Monro optimization algorithm, and Langevin dynamics, a mathematical extension of molecular dynamics models.
