Error bound of critical points and KL property of exponent for squared F-norm regularized factorization
Ting Tao, Shaohua Pan, Shujun Bi
This paper is concerned with the squared F(robenius)-norm regularized factorization form for noisy low-rank matrix recovery problems. Under a suitable assumption on the restricted…
A proximal dual semismooth Newton method for computing zero-norm penalized QR estimator
Dongdong Zhang, Shaohua Pan, Shujun Bi
This paper is concerned with the computation of the high-dimensional zero-norm penalized quantile regression estimator, defined as a global minimizer of the zero-norm penalized che…
Several classes of stationary points for rank regularized minimization problems
Yulan Liu, Shaohua Pan
For the rank regularized minimization problem, we introduce several kinds of stationary points by the problem itself and its equivalent reformulations including the mathematical pr…
KL property of exponent of quadratic functions under nonnegative zero-norm constraints and applications
Shaohua Pan, Yuqia Wu, Shujun Bi
This paper focuses on the quadratic optimization over two classes of nonnegative zero-norm constraints: nonnegative zero-norm sphere constraint and zero-norm simplex constraint, wh…
