Exponential stability for a nonlinear porous-elastic system with delay
M. J. Dos Santos, C. A. Raposo, L. G. R. Miranda +1
In this work, we consider the existence of global solution and the exponential decay of a nonlinear porous elastic system with time delay. The nonlinear term as well as the delay a…
Projectional Coderivatives and Calculus Rules
Wenfang Yao, Kaiwen Meng, Minghua Li +1
This paper is devoted to the study of a newly introduced tool, projectional coderivatives and the corresponding calculus rules in finite dimensions. We show that when the restricte…
Regularized Barzilai-Borwein method
Congpei An, Xin Xu
We develop a novel stepsize based on \BB method for solving some challenging optimization problems efficiently, named regularized \BB (RBB) stepsize. We indicate that RBB stepsize…
An adaptive low-rank splitting approach for the extended Fisher--Kolmogorov equation
Yong-Liang Zhao, Xian-Ming Gu
The extended Fisher--Kolmogorov (EFK) equation has been used to describe some phenomena in physical, material and biology systems. In this paper, we propose a full-rank splitting s…
Testing the martingale difference hypothesis in high dimension
Jinyuan Chang, Qing Jiang, Xiaofeng Shao
In this paper, we consider testing the martingale difference hypothesis for high-dimensional time series. Our test is built on the sum of squares of the element-wise max-norm of th…
Imputations for High Missing Rate Data in Covariates via Semi-supervised Learning Approach
Wei Lan, Xuerong Chen, Tao Zou +1
Advancements in data collection techniques and the heterogeneity of data resources can yield high percentages of missing observations on variables, such as block-wise missing data.…
Inward and Outward Network Influence Analysis
Yujia Wu, Wei Lan, Tao Zou +1
Measuring heterogeneous influence across nodes in a network is critical in network analysis. This paper proposes an Inward and Outward Network Influence (IONI) model to assess noda…
The free boundary of steady axisymmetric inviscid flow with vorticity I: near the degenerate point
Lili Du, Jinli Huang, Yang Pu
In this paper, we investigate the singularity near the degenerate points of the steady axisymmetric flow with general vorticity of an inviscid incompressible fluid acted on by grav…
On the quadrature exactness in hyperinterpolation
Congpei An, Hao-Ning Wu
This paper investigates the role of quadrature exactness in the approximation scheme of hyperinterpolation. Constructing a hyperinterpolant of degree requires a positive-weight…
Combining Intra-Risk and Contagion Risk for Enterprise Bankruptcy Prediction Using Graph Neural Networks
Yu Zhao, Shaopeng Wei, Yu Guo +6
Predicting the bankruptcy risk of small and medium-sized enterprises (SMEs) is an important step for financial institutions when making decisions about loans. Existing studies in b…
Human-Level Control through Directly-Trained Deep Spiking Q-Networks
Guisong Liu, Wenjie Deng, Xiurui Xie +2
As the third-generation neural networks, Spiking Neural Networks (SNNs) have great potential on neuromorphic hardware because of their high energy-efficiency. However, Deep Spiking…
Enhanced total variation minimization for stable image reconstruction
Congpei An, Hao-Ning Wu, Xiaoming Yuan
The total variation (TV) regularization has phenomenally boosted various variational models for image processing tasks. We propose to combine the backward diffusion process in the…
