The Ordered Weighted Norm: Atomic Formulation, Projections, and Algorithms
Xiangrong Zeng, Mário A. T. Figueiredo
The ordered weighted norm (OWL) was recently proposed, with two different motivations: its good statistical properties as a sparsity promoting regularizer; the fact that i…
Decreasing Weighted Sorted Regularization
Xiangrong Zeng, Mário A. T. Figueiredo
We consider a new family of regularizers, termed {\it weighted sorted norms} (WSL1), which generalizes the recently introduced {\it octagonal shrinkage and clustering algo…
Robust Binary Fused Compressive Sensing using Adaptive Outlier Pursuit
Xiangrong Zeng, Mário A. T. Figueiredo
We propose a new method, {\it robust binary fused compressive sensing} (RoBFCS), to recover sparse piece-wise smooth signals from 1-bit compressive measurements. The proposed metho…
Exploiting Two-Dimensional Group Sparsity in 1-Bit Compressive Sensing
Xiangrong Zeng, Mário A. T. Figueiredo
We propose a new approach, {\it two-dimensional fused binary compressive sensing} (2DFBCS) to recover 2D sparse piece-wise signals from 1-bit measurements, exploiting 2D group spar…
Group-sparse Matrix Recovery
Xiangrong Zeng, Mário A. T. Figueiredo
We apply the OSCAR (octagonal selection and clustering algorithms for regression) in recovering group-sparse matrices (two-dimensional---2D---arrays) from compressive measurements.…
Binary Fused Compressive Sensing: 1-Bit Compressive Sensing meets Group Sparsity
Xiangrong Zeng, Mário A. T. Figueiredo
We propose a new method, {\it binary fused compressive sensing} (BFCS), to recover sparse piece-wise smooth signals from 1-bit compressive measurements. The proposed algorithm is a…
