On Fienup Methods for Regularized Phase Retrieval
Edouard Pauwels, Amir Beck, Yonina C. Eldar +1
Alternating minimization, or Fienup methods, have a long history in phase retrieval. We provide new insights related to the empirical and theoretical analysis of these algorithms w…

GESPAR: Efficient Phase Retrieval of Sparse Signals
Yoav Shechtman, Amir Beck, Yonina C. Eldar
We consider the problem of phase retrieval, namely, recovery of a signal from the magnitude of its Fourier transform, or of any other linear transform. Due to the loss of the Fouri…

Sparsity Constrained Nonlinear Optimization: Optimality Conditions and Algorithms
Amir Beck, Yonina C. Eldar
This paper treats the problem of minimizing a general continuously differentiable function subject to sparsity constraints. We present and analyze several different optimality crit…
