The high-order block RIP for non-convex block-sparse compressed sensing
Jianwen Huang, Xinling Liu, Jinyao Hou +1
This paper concentrates on the recovery of block-sparse signals, which is not only sparse but also nonzero elements are arrayed into some blocks (clusters) rather than being arbitr…

On the distributional expansions of powered extremes from Maxwell distribution
Jianwen Huang, Xinling Liu, Jianjun Wang +3
In this paper, asymptotic expansions of the distributions and densities of powered extremes for Maxwell samples are considered. The results show that the convergence speeds of norm…
