One way to avoid overfitting in machine learning is to use model parameters distributed according to a Bayesian posterior given the data, rather than the maximum likelihood estimator. Stochastic gradient Langevin dynamics (SGLD) is one algorithm to approximate such Bayesian posteriors for large models and datasets. SGLD is a standard stochastic gradient descent to which is added a controlled

### Jun 13, 2012 In this article, we present several algorithms for stochastic dynamics, including In contrast, the simple Langevin dynamics will damp all velocities, including Combining Machine Learning and Molecular Dynamics to

In the Bayesian learning phase, we apply continuous tempering and stochastic approximation into the Langevin dynamics to create an efficient and effective sampler, in which the temperature is adjusted automatically according to the designed "temperature dynamics". In particular, we rethink the exploration-exploitation trade-off in RL as an instance of a distribution sampling problem in infinite dimensions. Using the powerful Stochastic Gradient Langevin Dynamics (SGLD), we propose a new RL algorithm, which results in a sampling variant of the Twin Delayed Deep Deterministic Policy Gradient (TD3) method.

It presents the concept of Stochastic Gradient Langevin Dynamics (SGLD). A method that nowadays is used increasingly. My motivation is to present the mathematical concepts that pushed SGLD forward.

The Langevin equation for time-dependent temperatures is usually interpreted as describing the decay of metastable physical states into the ground state of the Most MCMC algorithms have not been designed to process huge sample sizes, a typical setting in machine learning. As a result, many classical MCMC methods Sep 20, 2019 Deep neural networks trained with stochastic gradient descent algorithm proved to be extremely successful in number of applications such as Oct 31, 2020 Project: Bayesian deep learning and applications.
