Provable Sample-Efficient Sparse Phase Retrieval Initialized by Truncated Power Method
Jian-Feng Cai, Jingyang Li, Juntao You
We study the sparse phase retrieval problem, recovering an -sparse length- signal from magnitude-only measurements. Two-stage non-convex approaches have drawn much attent…
Structured Gradient Descent for Fast Robust Low-Rank Hankel Matrix Completion
HanQin Cai, Jian-Feng Cai, Juntao You
We study the robust matrix completion problem for the low-rank Hankel matrix, which detects the sparse corruptions caused by extreme outliers while we try to recover the original H…
Solving phase retrieval with random initial guess is nearly as good as by spectral initialization
Jianfeng Cai, Meng Huang, Dong Li +1
The problem of recovering a signal from a set of magnitude measurements is referred…
Accelerated Structured Alternating Projections for Robust Spectrally Sparse Signal Recovery
HanQin Cai, Jian-Feng Cai, Tianming Wang +1
Consider a spectrally sparse signal that consists of complex sinusoids with or without damping. We study the robust recovery problem for the spectrally sparse…
Towards the optimal construction of a loss function without spurious local minima for solving quadratic equations
Zhenzhen Li, Jian-Feng Cai, Ke Wei
The problem of finding a vector which obeys a set of quadratic equations , , plays an important role in many applications. In this paper we co…
Separation-Free Super-Resolution from Compressed Measurements is Possible: an Orthonormal Atomic Norm Minimization Approach
Weiyu Xu, Jirong Yi, Soura Dasgupta +3
We consider the problem of recovering the superposition of distinct complex exponential functions from compressed non-uniform time-domain samples. Total Variation (TV) minimiza…
