Phase Recovery, MaxCut and Complex Semidefinite Programming
, 2013 Phase retrieval seeks to recover a signal x from the amplitude |Ax| of linear measurements. We cast the phase retrieval problem as a non-convex quadratic program over a complex phase vector and formulate a tractable relaxation (called PhaseCut) similar ...

DOLPHIn - Dictionary Learning for Phase Retrieval [PDF]
, 2016 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 a two-dimensional image from squared-magnitude measurements of a complex ...

Solving systems of phaseless equations via Kaczmarz methods: A proof of concept study [PDF]
, 2015 We study the Kaczmarz methods for solving systems of quadratic equations, i.e., the generalized phase retrieval problem. The methods extend the Kaczmarz methods for solving systems of linear equations by integrating a phase selection heuristic in each ...

Unfolded Algorithms for Deep Phase Retrieval
AlgorithmsExploring the idea of phase retrieval has been intriguing researchers for decades due to its appearance in a wide range of applications. The task of a phase retrieval algorithm is typically to recover a signal from linear phase-less measurements. In this

Effects of cue focality on the neural mechanisms of prospective memory: A meta-analysis of neuroimaging studies [PDF]
, 2016 Remembering to execute pre-defined intentions at the appropriate time in the future is typically referred to as Prospective Memory (PM). Studies of PM showed that distinct cognitive processes underlie the execution of delayed intentions depending on ...
