Linear Opinion Dynamics Model with Higher-Order Interactions
Wanyue Xu, Zhongzhi Zhang
Opinion dynamics is a central subject of computational social science, and various models have been developed to understand the evolution and formulation of opinions. Existing mode…
Diagonal of Pseudoinverse of Graph Laplacian: Fast Estimation and Exact Results
Zenan Lu, Wanyue Xu, Zhongzhi Zhang
The diagonal entries of pseudoinverse of the Laplacian matrix of a graph appear in many important practical applications, since they contain much information of the graph and many…
Minimizing Polarization in Noisy Leader-Follower Opinion Dynamics
Wanyue Xu, Zhongzhi Zhang
The operation of creating edges has been widely applied to optimize relevant quantities of opinion dynamics. In this paper, we consider a problem of polarization optimization for t…
ConvFormer: Revisiting Transformer for Sequential User Modeling
Hao Wang, Jianxun Lian, Mingqi Wu +5
Sequential user modeling, a critical task in personalized recommender systems, focuses on predicting the next item a user would prefer, requiring a deep understanding of user behav…
Optimal Scale-Free Small-World Graphs with Minimum Scaling of Cover Time
Wanyue Xu, Zhongzhi Zhang
The cover time of random walks on a graph has found wide practical applications in different fields of computer science, such as crawling and searching on the World Wide Web and qu…
Combinatorial Properties for a Class of Simplicial Complexes Extended from Pseudo-fractal Scale-free Web
Zixuan Xie, Yucheng Wang, Wanyue Xu +3
Simplicial complexes are a popular tool used to model higher-order interactions between elements of complex social and biological systems. In this paper, we study some combinatoria…
