Sparse Portfolio Selection via Non-convex Fraction Function
Angang Cui, Jigen Peng, Chengyi Zhang +2
In this paper, a continuous and non-convex promoting sparsity fraction function is studied in two sparse portfolio selection models with and without short-selling constraints. Firs…
An Improved LPTC Neural Model for Background Motion Direction Estimation
Hongxin Wang, Jigen Peng, Shigang Yue
A class of specialized neurons, called lobula plate tangential cells (LPTCs) has been shown to respond strongly to wide-field motion. The classic model, elementary motion detector…
Recovering Sparse Nonnegative Signals via Non-convex Fraction Function Penalty
Angang Cui, Haiyang Li, Meng Wen +1
Many real world practical problems can be formulated as -minimization problems with nonnegativity constraints, which seek the sparsest nonnegative signals to underdetermi…
Studies on an inverse source problem for a space-time fractional diffusion equation by constructing a strong maximum principle
Junxiong Jia, Jigen Peng, Jiaqing Yang
In this paper, we focus on a space-time fractional diffusion equation with the generalized Caputo's fractional derivative operator and a general space nonlocal operator (with the f…
An inertial primal-dual fixed point algorithm for composite optimization problems
Meng Wen, Yu-Chao Tang, Jigen Peng
We consider an inertial primal-dual fixed point algorithm (IPDFP) to compute the minimizations of the following Problem (1.1). This is a full splitting approach, in the sense that…
Efficient primal-dual fixed point algorithm with dynamic stepsize for convex problems with applications to imaging restoration
Meng Wen, Shigang Yue, Yuchao Tang +1
We consider the problem of finding the minimization of the sum of a convex function and the composition of another convex function with a continuous linear operator from the view o…
