Gauger (University of Kaiserslautern-Landau), R. Jerbi, and A. Sior (Université de Liège).
Objectives
The goal of this associate team is to develop innovative approaches inspired by the one-shot paradigm, which simultaneously solve the forward and inverse problems in a way that optimally exploits the specificity of an iterative forward solver, for instance based on domain decomposition approaches for large scale problems. Our aim is (i) speeding up the overall convergence rate for inversion methods and (ii) efficiently addressing inverse large scale (and/or time dependent) problems by reducing the number of forward solves.
