On Assignment Problems Related to Gromov-Wasserstein Distances on the Real Line
Robert Beinert, Cosmas Heiss, Gabriele Steidl
Let and , , be real numbers. We show by an example that the assignment problem $$ \max_{σ\in S_n} F_σ(x,y) := \frac12 \sum_{…
Approximation of Curve-based Sleeve Functions in High Dimensions
Robert Beinert
Sleeve functions are generalizations of the well-established ridge functions that play a major role in the theory of partial differential equation, medical imaging, statistics, and…
Phase Retrieval and System Identification in Dynamical Sampling via Prony's Method
Robert Beinert, Marzieh Hasannasab
Phase retrieval in dynamical sampling is a novel research direction, where an unknown signal has to be recovered from the phaseless measurements with respect to a dynamical frame,…
Phase Retrieval via Polarization in Dynamical Sampling
Robert Beinert, Marzieh Hasannasab
In this paper we consider the nonlinear inverse problem of phase retrieval in the context of dynamical sampling. Where phase retrieval deals with the recovery of signals & images f…
Super-Resolution for Doubly-Dispersive Channel Estimation
Robert Beinert, Peter Jung, Gabriele Steidl +1
In this work we consider the problem of identification and reconstruction of doubly-dispersive channel operators which are given by finite linear combinations of time-frequency shi…
Robust PCA via Regularized REAPER with a Matrix-Free Proximal Algorithm
Robert Beinert, Gabriele Steidl
Principal component analysis (PCA) is known to be sensitive to outliers, so that various robust PCA variants were proposed in the literature. A recent model, called REAPER, aims to…
