New Accumulative Score Function Based Bound For Sparsity Level of L1 Minimization

Sheng Han, Suzhen Wang, Zhiguo Zhang

This paper discusses a fundamental problem in compressed sensing: the sparse recoverability of L1 minimization with an arbitrary sensing matrix. We develop an new accumulative scor…

$l_{1}$ -regularized Outlier Isolation and Regression

Sheng Han, Suzhen Wang, Xinyu Wu

This paper proposed a new regression model called $l_{1}$ -regularized outlier isolation and regression (LOIRE) and a fast algorithm based on block coordinate descent to solve this mo…
