Enhancement of signal-to-noise ratio at a high-order exceptional point of coherent perfect absorption
Zi-Qi Wang, Yi-Ming Sun, Yao-Dong Hu +4
Exceptional points (EPs) in non-Hermitian systems offer a remarkably strong response to weak perturbations, but the nonorthogonal nature of the corresponding eigenvectors causes no…
Regularization for Sparse Optimization: Consistency and Global Convergence
Yaohua Hu, Hao Wang, Xiaoqi Yang
The regularization method has a strong sparsity promoting capability in approaching sparse solutions of linear inverse problems and gained successful applicatio…
Dynamic Proximal Gradient Algorithms for Schatten- Quasi-Norm Regularized Problems
Weiping Shen, Linglingzhi Zhu, Yaohua Hu +2
This paper investigates numerical solution methods for the Schatten- quasi-norm regularized problem with , which has been widely studied for finding low-rank soluti…
A Globalized Semismooth Newton Method for Prox-regular Optimization Problems
Yuqia Wu, Pengcheng Wu, Yaohua Hu +2
We are concerned with a class of nonconvex and nonsmooth composite optimization problems, comprising a twice differentiable function and a prox-regular function. We establish a suf…
