Inverse Scale Space Decomposition
Marie Foged Schmidt, Martin Benning, Carola-Bibiane Schönlieb
We investigate the inverse scale space flow as a decomposition method for decomposing data into generalised singular vectors. We show that the inverse scale space flow, based on co…
Gradient descent in a generalised Bregman distance framework
Martin Benning, Marta M. Betcke, Matthias J. Ehrhardt +1
We discuss a special form of gradient descent that in the literature has become known as the so-called linearised Bregman iteration. The idea is to replace the classical (squared)…
Explorations on anisotropic regularisation of dynamic inverse problems by bilevel optimisation
Martin Benning, Carola-Bibiane Schönlieb, Tuomo Valkonen +1
We explore anisotropic regularisation methods in the spirit of [Holler & Kunisch, 14]. Based on ground truth data, we propose a bilevel optimisation strategy to compute the optimal…
