Our algorithm consistently outperforms existing baselines, in terms of generalization 2011-10-17 · Langevin Dynamics In Langevin dynamics we take gradient steps with constant valued and add gaussian noise Based o using the posterior as an equilibrium distribution All of the data is used, i.e. there is no batch Langevin Dynamics We update by using the equation and use the updated value as a M-H proposal: t = 2 rlog p( t) + XN i=1 rlog p(x ij Abstract: Stochastic gradient descent with momentum (SGDm) is one of the most popular optimization algorithms in deep learning. While there is a rich theory of SGDm for convex problems, the theory is considerably less developed in the context of deep learning where the problem is non-convex and the gradient noise might exhibit a heavy-tailed behavior, as empirically observed in recent studies. The Langevin equation for time-dependent temperatures is usually interpreted as describing the decay of metastable physical states into the ground state of the Most MCMC algorithms have not been designed to process huge sample sizes, a typical setting in machine learning. As a result, many classical MCMC methods Sep 20, 2019 Deep neural networks trained with stochastic gradient descent algorithm proved to be extremely successful in number of applications such as Oct 31, 2020 Project: Bayesian deep learning and applications. Authors We apply Langevin dynamics in neural networks for chaotic time series prediction.

In this study, we consider a continuous-time variant of SGDm, known as the underdamped Langevin dynamics (ULD), and investigate its asymptotic properties under heavy-tailed pertur-bations. deep neural network model is essential to show superiority of deep learning over linear estimators such as kernel methods as in the analysis of [65, 30, 66]. Therefore, the NTK regime would not be appropriate to show superiority of deep learning over other methods such as kernel methods.

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 amount of noise, specifically scaled so that the parameter converges in law to the posterior distribution [WT11, TTV16].
