On Collaborative Compressive Sensing Systems: The Framework, Design and Algorithm
Zhihui Zhu, Gang Li, Jiajun Ding +2
Based on the maximum likelihood estimation principle, we derive a collaborative estimation framework that fuses several different estimators and yields a better estimate. Applying…
The Global Optimization Geometry of Low-Rank Matrix Optimization
Zhihui Zhu, Qiuwei Li, Gongguo Tang +1
This paper considers general rank-constrained optimization problems that minimize a general objective function over the set of rectangular matrices that have ran…
Global Optimality in Low-rank Matrix Optimization
Zhihui Zhu, Qiuwei Li, Gongguo Tang +1
This paper considers the minimization of a general objective function over the set of rectangular matrices that have rank at most . To reduce the computationa…
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)…
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…
