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.

Natural Langevin Dynamics for Neural Networks. 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.

It was originally developed by French physicist Paul Langevin . The approach is characterized by the use of simplified models while accounting for omitted degrees of freedom by the use of stochastic differential equations . MCMC methods are widely used in machine learning, but applications of Langevin dynamics to machine learning only start to appear Welling and Teh ; Ye et al.
