A variational analysis of stochastic gence of stochastic gradient MCMC algorithms (SG-MCMC), such as stochas-tic gradient Langevin dynamics (SGLD), stochastic gradient Hamiltonian MCMC (SGHMC), and the stochastic gradient thermostat.

This move assigns a velocity from the Maxwell-Boltzmann distribution and executes a number of Maxwell-Boltzmann steps to propagate dynamics. tional MCMC methods use the full dataset, which does not scale to large data problems. A pioneering work in com-bining stochastic optimization with MCMC was presented in (Welling and Teh 2011), based on Langevin dynam-ics (Neal 2011). This method was referred to as Stochas-tic Gradient Langevin Dynamics (SGLD), and required only HYBRID GRADIENT LANGEVIN DYNAMICS FOR BAYESIAN LEARNING 223 are also some variants of the method, for example, pre-conditioning the dynamic by a positive deﬁnite matrix A to obtain (2.2) dθt = 1 2 A∇logπ(θt)dt +A1/2dWt.

### MCMC [25], such as nite step Langevin dynamics, as an approximate inference engine. In the learning process, for each training example, we always initialize such a short run MCMC from the prior distribution of the latent variables, such as Gaussian or uniform noise …

To construct an irreversible algorithm on Lie groups, we first extend Langevin dynamics to general symplectic manifolds M based on Bismut’s symplectic diffusion process [bismut1981mecanique].Our generalised Langevin dynamics with multiplicative noise and nonlinear dissipation has the Gibbs measure as the invariant measure, which allows us to design MCMC algorithms that sample from a Lie Langevin dynamics MCMC for training neural networks.
