Space-time reduced order model for large-scale linear dynamical systems with application to Boltzmann transport problems
Youngsoo Choi, Peter Brown, Bill Arrighi +1
A classical reduced order model for dynamical problems involves spatial reduction of the problem size. However, temporal reduction accompanied by the spatial reduction can further…

SNS: A Solution-based Nonlinear Subspace method for time-dependent model order reduction
Youngsoo Choi, Deshawn Coombs, Robert Anderson
Several reduced order models have been developed for nonlinear dynamical systems. To achieve a considerable speed-up, a hyper-reduction step is needed to reduce the computational c…
