A sufficient condition for the existence of solutions of singular linear-quadratic vector equations
Rishikesh Yadav, Axel Flinth
We study the existence of solutions for systems of linear-quadratic vector equations with singular linear parts. We derive a sufficient condition for small right hand sides.
Recovery of Binary Sparse Signals with Biased Measurement Matrices
Axel Flinth, Sandra Keiper
This work treats the recovery of sparse, binary signals through box-constrained basis pursuit using biased measurement matrices. Using a probabilistic model, we provide conditions…
Soft Recovery With General Atomic Norms
Axel Flinth
This paper describes a dual certificate condition on a linear measurement operator (defined on a Hilbert space and having finite-dimensional range) which guarante…
Soft Recovery Through Minimization with Applications in Recovery of Simultaneously Sparse and Low-Rank Matrice
Axel Flinth
This article provides a new type of analysis of a compressed-sensing based technique for recovering column-sparse matrices, namely minimization of the -norm. Rather tha…
