An equivalent reformulation and multi-proximity gradient algorithms for a class of nonsmooth fractional programming
Junpeng Zhou, Na Zhang, Qia Li
In this paper, we consider a class of structured fractional programs, where the numerator part is the sum of a block-separable (possibly nonsmooth nonconvex) function and a locally…
A Successive Two-stage Method for Sparse Generalized Eigenvalue Problems
Qia Li, Jianmin Liao, Lixin Shen +1
The Sparse Generalized Eigenvalue Problem (sGEP), a pervasive challenge in statistical learning methods including sparse principal component analysis, sparse Fisher's discriminant…
Parameterized proximal-gradient algorithms for L1/L2 sparse signal recovery
Na Zhang, Xinrui Liu, Qia Li
The ratio of L1 and L2 norms (L1/L2), serving as a sparse promoting function, receives considerable attentions recently due to its effectiveness for sparse signal recovery. In this…
Smoothing algorithms for nonsmooth and nonconvex minimization over the stiefel manifold
Jinlai Zhu, Jianfeng Huang, Lihua Yang +1
We consider a class of nonsmooth and nonconvex optimization problems over the Stiefel manifold where the objective function is the summation of a nonconvex smooth function and a no…
