Accelerating Convergence of Replica Exchange Stochastic Gradient MCMC via Variance Reduction

Wei Deng, Qi Feng, Georgios Karagiannis +2

Replica exchange stochastic gradient Langevin dynamics (reSGLD) has shown promise in accelerating the convergence in non-convex learning; however, an excessively large correction f…

Multifidelity Data Fusion via Gradient-Enhanced Gaussian Process Regression

Yixiang Deng, Guang Lin, Xiu Yang

We propose a data fusion method based on multi-fidelity Gaussian process regression (GPR) framework. This method combines available data of the quantity of interest (QoI) and its g…
