Approximate Support Recovery of Atomic Line Spectral Estimation: A Tale of Resolution and Precision
Qiuwei Li, Gongguo Tang
This work investigates the parameter estimation performance of super-resolution line spectral estimation using atomic norm minimization. The focus is on analyzing the algorithm's a…
The Non-convex Geometry of Low-rank Matrix Optimization
Qiuwei Li, Zhihui Zhu, Gongguo Tang
This work considers two popular minimization problems: (i) the minimization of a general convex function with the domain being positive semi-definite matrices; (ii)…
Demixing Sines and Spikes: Robust Spectral Super-resolution in the Presence of Outliers
Carlos Fernandez-Granda, Gongguo Tang, Xiaodong Wang +1
We consider the problem of super-resolving the line spectrum of a multisinusoidal signal from a finite number of samples, some of which may be completely corrupted. Measurements of…
A Super-Resolution Framework for Tensor Decomposition
Qiuwei Li, Ashley Prater, Lixin Shen +1
This work considers a super-resolution framework for overcomplete tensor decomposition. Specifically, we view tensor decomposition as a super-resolution problem of recovering a sum…
Super-Resolution of Complex Exponentials from Modulations with Unknown Waveforms
Dehui Yang, Gongguo Tang, Michael B. Wakin
Super-resolution is generally referred to as the task of recovering fine details from coarse information. Motivated by applications such as single-molecule imaging, radar imaging,…
