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…
Accelerated Alternating Projections for Robust Principal Component Analysis
HanQin Cai, Jian-Feng Cai, Ke Wei
We study robust PCA for the fully observed setting, which is about separating a low rank matrix and a sparse matrix from their sum $\boldsymbol{D}…
Fast Rank One Alternating Minimization Algorithm for Phase Retrieval
Jian-Feng Cai, Haixia Liu, Yang Wang
The phase retrieval problem is a fundamental problem in many fields, which is appealing for investigation. It is to recover the signal vector from a set…
Spectral Compressed Sensing via Projected Gradient Descent
Jian-Feng Cai, Tianming Wang, Ke Wei
Let be a spectrally sparse signal consisting of complex sinusoids with or without damping. We consider the spectral compressed sensing problem, which is abou…
Accelerated Magnetic Resonance Spectroscopy with Vandermonde Factorization
Xiaobo Qu, Jiaxi Ying, Jian-Feng Cai +1
Multi-dimensional magnetic resonance spectroscopy is an important tool for studying molecular structures, interactions and dynamics in bio-engineering. The data acquisition time, h…
