Also, Langevin dynamics allows temperature to be controlled like with a thermostat, thus approximating the canonical ensemble. Langevin dynamics mimics the viscous aspect of a solvent. Stochastic gradient Langevin dynamics, 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. Like stochastic gradient descent, SGLD is an iterative optimization algorithm which introduces additional noise to the stochastic gradient estimator used in SGD to optimize a differentiable objective function.

SGLD is a standard stochastic gradient descent to which is added a controlled Inverse reinforcement learning (IRL) aims to estimate the reward function of optimizing agents by observing their response (estimates or actions). This paper considers IRL when noisy estimates of the gradient of a reward function generated by multiple stochastic gradient agents are observed. Natural Langevin Dynamics for Neural Networks .

Here, is our learning rate for step . 1. Introduction. This work focuses on Bayesian learning based on a hybrid deterministic-stochastic gradient descent Langevin dynamics. There has been increas-ing interest in large scale datasets for machine learning, ranging from network data, signal processing and data mining to bioinformatics. The large scale data significantly Stochastic Gradient Langevin Dynamics (SGLD) is an effective method to enable Bayesian deep learning on large-scale datasets.

2021-03-30 · Stochastic Gradient Langevin Dynamics for Bayesian learning. This was a final project for Berkeley's EE126 class in Spring 2019: Final Project Writeup. This respository contains code to reproduce and analyze the results of the paper "Bayesian Learning via Stochastic Gradient Langevin Dynamics". We present a unified framework to analyze the global convergence of Langevin dynamics based algorithms for nonconvex finite-sum optimization with n compo-nent functions. At the core of our analysis is a direct analysis of the ergodicity of the numerical approximations to Langevin dynamics, which leads to faster convergence rates.

On Langevin Dynamics in Machine Learning. Langevin diffusions are continuous-time stochastic processes that are based on the gradient of a potential function. As such they have many connections---some known and many still to be explored---to gradient-based machine learning.
