On NP-Hardness of Minimization and Bound Theory of Nonzero Entries in Solutions
Min Tao, Xiao-Ping Zhang, Yun-Bin Zhao
The \(L_1/L_2\) norm ratio has gained significant attention as a measure of sparsity due to three merits: sharper approximation to the \(L_0\) norm compared to the \(L_1\) norm, be…
On Partly Smoothness, Activity Identification and Faster Algorithms of over Minimization
Min Tao, Xiao-Ping Zhang, Zi-Hao Xia
The norm ratio arose as a sparseness measure and attracted a considerable amount of attention due to three merits: (i) sharper approximations of compared to the $L_…
The First and Second-Order Asymptotics of Covert Communication over AWGN Channels
Xinchun Yu, Shuangqing Wei, Shao-Lun Huang +1
This paper investigates the asymptotics of the maximal throughput of communication over AWGN channels by channel uses under a covert constraint in terms of an upper bound o…
Unified Analysis on L1 over L2 Minimization for signal recovery
Min Tao, Xiao-Ping Zhang
In this paper, we carry out a unified study for over sparsity promoting models, which are widely used in the regime of coherent dictionaries for recovering sparse nonne…
