Linear Convergence of Adaptively Iterative Thresholding Algorithms for Compressed Sensing

Yu Wang, Jinshan Zeng, Zhimin Peng +2

This paper studies the convergence of the adaptively iterative thresholding (AIT) algorithm for compressed sensing. We first introduce a generalized restricted isometry property (g…

Sparse K-Means with $ℓ_{\infty} / ℓ_{0}$ Penalty for High-Dimensional Data Clustering

Xiangyu Chang, Yu Wang, Rongjian Li +1

Sparse clustering, which aims to find a proper partition of an extremely high-dimensional data set with redundant noise features, has been attracted more and more interests in rece…
