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. 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 We re-think the exploration-exploitation trade-off in reinforcement learning (RL) as an instance of a distribution sampling problem in inﬁnite dimensions. Using the powerful Stochastic Gradient Langevin Dynamics, we propose a new RL algorithm, which is a sampling variant of the Twin Delayed Deep Deterministic Policy Gradient (TD3) method. The idea of combining Energy-Based models, deep neural network, and Langevin dynamics provides an elegant, efficient, and powerful way to synthesize high-dimensional data with high quality.
