A Primal-Dual Homotopy Algorithm for -Minimization with -Constraints
Christoph Brauer, Dirk A. Lorenz, Andreas M. Tillmann
In this paper we propose a primal-dual homotopy method for -minimization problems with infinity norm constraints in the context of sparse reconstruction. The natural homoto…
Sparse Recovery With Integrality Constraints
Jan-Hendrik Lange, Marc E. Pfetsch, Bianca M. Seib +1
We investigate conditions for the unique recoverability of sparse integer-valued signals from a small number of linear measurements. Both the objective of minimizing the number of…
DOLPHIn - Dictionary Learning for Phase Retrieval
Andreas M. Tillmann, Yonina C. Eldar, Julien Mairal
We propose a new algorithm to learn a dictionary for reconstructing and sparsely encoding signals from measurements without phase. Specifically, we consider the task of estimating…
