Efficient iterative thresholding algorithms with functional feedbacks and convergence analysis
Ningning Han, Shidong Li, Zhanjie Song
An accelerated class of adaptive scheme of iterative thresholding algorithms is studied analytically and empirically. They are based on the feedback mechanism of the null space tun…
The convergence guarantee of the iterative thresholding algorithm with suboptimal feedbacks for large systems
Zhanjie Song, Shidong Li, Ningning Han
Thresholding based iterative algorithms have the trade-off between effectiveness and optimality. Some are effective but involving sub-matrix inversions in every step of iterations.…
Spark Level Sparsity and the Tail Minimization
Chun-Kit Lai, Shidong Li, Daniel Mondo
Solving compressed sensing problems relies on the properties of sparse signals. It is commonly assumed that the sparsity s needs to be less than one half of the spark of the sensin…
Local sparsity and recovery of fusion frames structured signals
Roza Aceska, Jean-Luc Bouchot, Shidong Li
The problem of recovering signals of high complexity from low quality sensing devices is analyzed via a combination of tools from signal processing and harmonic analysis. By using…
