Abstract We present an introduction to some of the state art in reduced order and surrogate modeling gravitational-wave (GW) science. Approaches that we cover include principal component analysis, proper orthogonal (singular value) decompositions, basis approach, empirical interpolation method, quadratures, compressed likelihood evaluations. divide review into three parts: representation/compre...

In this paper, we develop data-driven closure/correction terms to increase the pressure and velocity accuracy of reduced order models (ROMs) for fluid flows. Specifically, propose first pressure-based variational multiscale ROM, in which use available data construct both momentum equation continuity equation. Our numerical investigation two-dimensional flow past a circular cylinder at Re=50,000...

In this work, we present a reduced-order model for nonlinear cross-diffusion problem from population dynamics, the Shigesada-Kawasaki-Teramoto (SKT) equation with Lotka-Volterra kinetics. The finite-difference discretization of SKT in space results system linear--quadratic ordinary differential equations (ODEs). reduced order (ROM) has same linear-quadratic structure as full (FOM). Using ROM, s...
