Compressing Large-Scale Wave Propagation Models via Phase-Preconditioned Rational Krylov Subspaces
Vladimir Druskin, Rob Remis, Mikhail Zaslavsky +1
Rational Krylov subspace (RKS) techniques are well-established and powerful tools for projection-based model reduction of time-invariant dynamic systems. For hyperbolic wavefield p…
Untangling the nonlinearity in inverse scattering with data-driven reduced order models
Liliana Borcea, Vladimir Druskin, Alexander V. Mamonov +1
The motivation of this work is an inverse problem for the acoustic wave equation, where an array of sensors probes an unknown medium with pulses and measures the scattered waves. T…
A nonlinear method for imaging with acoustic waves via reduced order model backprojection
Vladimir Druskin, Alexander V. Mamonov, Mikhail Zaslavsky
We introduce a novel nonlinear imaging method for the acoustic wave equation based on data-driven model order reduction. The objective is to image the discontinuities of the acoust…
