Regularization Graphs -- A unified framework for variational regularization of inverse problems
Kristian Bredies, Marcello Carioni, Martin Holler
We introduce and study a mathematical framework for a broad class of regularization functionals for ill-posed inverse problems: Regularization Graphs. Regularization graphs allow t…
Asymptotic linear convergence of fully-corrective generalized conditional gradient methods
Kristian Bredies, Marcello Carioni, Silvio Fanzon +1
We propose a fully-corrective generalized conditional gradient method (FC-GCG) for the minimization of the sum of a smooth, convex loss function and a convex one-homogeneous regula…
Degenerate Preconditioned Proximal Point algorithms
Kristian Bredies, Enis Chenchene, Dirk A. Lorenz +1
In this paper we describe a systematic procedure to analyze the convergence of degenerate preconditioned proximal point algorithms. We establish weak convergence results under mild…
