An Adaptive EM Accelerator for Unsupervised Learning of Gaussian Mixture Models
Truong Nguyen, Guangye Chen, Luis Chacon
We propose an Anderson Acceleration (AA) scheme for the adaptive Expectation-Maximization (EM) algorithm for unsupervised learning a finite mixture model from multivariate data (Fi…

A semi-implicit, energy- and charge-conserving particle-in-cell algorithm for the relativistic Vlasov-Maxwell equations
Guangye Chen, Luis Chacón, Lin Yin +3
Conventional explicit electromagnetic particle-in-cell (PIC) algorithms do not conserve discrete energy exactly. Time-centered fully implicit PIC algorithms can conserve discrete e…

A Multigroup Moment-Accelerated Deterministic Particle Solver for Time-dependent Thermal Radiative Transfer Problems
H. Park, L. Chacon, A. Matsekh +1
We propose an efficient, robust, Lagrangian (characteristic-based) transport solver for the time-dependent thermal radiative Transfer (TRT) applications within the context of a mom…
