Riemannian thresholding methods for row-sparse and low-rank matrix recovery
Henrik Eisenmann, Felix Krahmer, Max Pfeffer +1
In this paper, we present modifications of the iterative hard thresholding (IHT) method for recovery of jointly row-sparse and low-rank matrices. In particular a Riemannian version…
On recovery guarantees for angular synchronization
Frank Filbir, Felix Krahmer, Oleh Melnyk
The angular synchronization problem of estimating a set of unknown angles from their known noisy pairwise differences arises in various applications. It can be reformulated as a op…
The Homotopy Method Revisited: Computing Solution Paths of -Regularized Problems
Björn Bringmann, Daniel Cremers, Felix Krahmer +1
-regularized linear inverse problems are frequently used in signal processing, image analysis, and statistics. The correct choice of the regularization parameter $ t \in…
