GLIP: Graph and LLM Joint Pretraining for Graph-Level Tasks
Haoxin Sun, Yiqing Lin, Yajun Huang +3
Graphs are widely used to model relational systems, with applications in domains such as social networks, finance, and biomedicine. Graph neural networks (GNNs) have become a mains…
Fast Estimation for Forest Matrix of Signed Graphs
Haoxin Sun, Zhongzhi Zhang
The forest matrix of a signed graph plays an important role in network science and social opinion dynamics, yet existing algorithms are mainly designed for unsigned graphs and are…
Efficient Computation for Diagonal of Forest Matrix via Variance-Reduced Forest Sampling
Haoxin Sun, Zhongzhi Zhang
The forest matrix of a graph, particularly its diagonal elements, has far-reaching implications in network science and machine learning. The state-of-the-art algorithms for the dia…
Efficient Edge Rewiring Strategies for Enhancing PageRank Fairness
Changan Liu, Haoxin Sun, Ahad N. Zehmakan +1
We study the notion of unfairness in social networks, where a group such as females in a male-dominated industry are disadvantaged in access to important information, e.g. job post…
