Learning Bounded Koopman Observables: Results on Stability, Continuity, and Controllability
Craig Bakker, Thiagarajan Ramachandran, W. Steven Rosenthal
The Koopman operator is an useful analytical tool for studying dynamical systems -- both controlled and uncontrolled. For example, Koopman eigenfunctions can provide non-local stab…
Trimmed Ensemble Kalman Filter for Nonlinear and Non-Gaussian Data Assimilation Problems
Weixuan Li, W. Steven Rosenthal, Guang Lin
We study the ensemble Kalman filter (EnKF) algorithm for sequential data assimilation in a general situation, that is, for nonlinear forecast and measurement models with non-additi…
PDF estimation for power grid systems via sparse regression
Xiu Yang, David A. Barajas-Solano, W. Steven Rosenthal +1
We present a numerical approach for estimating the probability density function (PDF) of quantities of interest (QoIs) of power grid systems subject to uncertain power generation a…
Displacement Data Assimilation
W. Steven Rosenthal, Shankar C. Venkataramani, Arthur J. Mariano +1
We show that modifying a Bayesian data assimilation scheme by incorporating kinematically-consistent displacement corrections produces a scheme that is demonstrably better at estim…
