Stochastic Gradient Langevin Dynamics (SGLD) is a popular variant of Stochastic Gradient Descent, where properly scaled isotropic Gaussian noise is added to 

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.

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.

Stochastic Gradient Langevin Dynamics (SGLD) is an effective method to enable Bayesian deep learning on large-scale datasets. Previous theoretical studies have shown various appealing properties of SGLD, ranging from the convergence properties to the generalization bounds.

We can write the mini-batch gradient as a sum between the full gradient and a normally distributed η: We propose an adaptively weighted stochastic gradient Langevin dynamics algorithm (SGLD), so-called contour stochastic gradient Langevin dynamics (CSGLD), for Bayesian learning in big data statistics. The proposed algorithm is essentially a \\emph{scalable dynamic importance sampler}, which automatically \\emph{flattens} the target distribution such that the simulation for a multi-modal Welling, M., Teh, Y.W.: Bayesian learning via stochastic gradient Langevin dynamics.

Stochastic Gradient Langevin Dynamics Vanilla SGD. Let’s write a traditional SGD update step. It’s very much like our equation above, except now we calculate our energy on a subset of the data. We’ll write that energy , for energy (loss function) of the minibatch at time . 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.

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].

The gradient descent algorithm is one of the most popular optimization techniques in machine learning. It comes in three flavors: batch or “vanilla” gradient descent (GD), stochastic gradient descent (SGD), and mini-batch gradient descent which differ in the amount of data used to compute the gradient of the loss function at each iteration. In this paper, we propose to adapt the methods of molecular and Langevin dynamics to the problems of nonconvex optimization, that appear in machine learning.
