Nonlinear Parametric Inversion Using Interpolatory Model Reduction

Nonlinear parametric inverse problems appear in several prominent applications; one such application is diffuse optical tomography (DOT) in medical image reconstruction. Such inverse problems present huge computational challenges, mostly due to the need for solving a sequence of large-scale discretized, parametrized partial differential equations in the forward model. In this paper, we show how interpolatory parametric model reduction can...
