Salt Reconstruction in Full Waveform Inversion with a Parametric Level-Set Method
Ajinkya Kadu, Tristan van Leeuwen, Wim A. Mulder
Seismic full-waveform inversion tries to estimate subsurface medium parameters from seismic data. Areas with subsurface salt bodies are of particular interest because they often ha…
Efficient quadratic penalization through the partial minimization technique
Aleksandr Y. Aravkin, Dmitriy Drusvyatskiy, Tristan van Leeuwen
Common computational problems, such as parameter estimation in dynamic models and PDE constrained optimization, require data fitting over a set of auxiliary parameters subject to p…
Non-smooth Variable Projection
Tristan van Leeuwen, Aleksandr Aravkin
Variable projection solves structured optimization problems by completely minimizing over a subset of the variables while iterating over the remaining variables. Over the last 30 y…
