A comparative study of structural similarity and regularization for joint inverse problems governed by PDEs
Benjamin Crestel, Georg Stadler, Omar Ghattas
Joint inversion refers to the simultaneous inference of multiple parameter fields from observations of systems governed by single or multiple forward models. In many cases these pa…

A-optimal encoding weights for nonlinear inverse problems, with applications to the Helmholtz inverse problem
Benjamin Crestel, Alen Alexanderian, Georg Stadler +1
The computational cost of solving an inverse problem governed by PDEs, using multiple experiments, increases linearly with the number of experiments. A recently proposed method to…
