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. Unlike traditional SGD, SGLD can be

Inferring Langevin equations from data can reveal how transient dynamics of such systems give rise to their function. However, dynamics are often inaccessible directly and can be only gleaned through a stochastic observation process, which makes the inference algorithm for deep learning and big data problems. 2.3 Related work Compared to the existing MCMC algorithms, the proposed algorithm has a few innovations: First, CSGLD is an adaptive MCMC algorithm based on the Langevin transition kernel instead of the Metropolis transition kernel [Liang et al., 2007, Fort et al., 2015]. As a result, the existing Machine Learning and Physics: Gradient Descent as a Langevin Process. The next (and last) step is crucial for the argument.

The algorithm is as follows. However, there is a caveat in step 7 that is not properly addressed in the paper. This algorithm is for 1 iteration: ε: thermal noise; Fix: L, ε, η; Step 7: As the authors stress, γ has to be tuned (scoping). 2017-12-04 · 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.
