Sequential Bayesian parameter-state estimation in dynamical systems with noisy and incomplete observations via a variational framework
Liliang Wang, Alex Gorodetsky
Online joint estimation of a dynamical model's unknown parameters and states with uncertainty quantification is crucial in many applications. For example, digital twins dynamically…

Multigroup Thermal Radiation Transport with Tensor Trains
Aditya S. Deshpande, Patrick D. Mullen, Alex A. Gorodetsky +4
We investigate the application of tensor-train (TT) algorithms to multigroup thermal radiation transport (i.e., photon radiation transport). The TT framework enables simulations at…

A global Lipschitz stability perspective for understanding approximate approaches in Bayesian sequential learning
Liliang Wang, Alex A. Gorodetsky
We establish a general, non-asymptotic error analysis framework for understanding the effects of incremental approximations made by practical approaches for Bayesian sequential lea…
