Subjective-Graph LLM Agents for Simulating Uncertainty in Classroom Social Perception
Jinming Yang, Xinyu Jiang, Xinshan Jiao +1
Social actors do not observe a common social world: each individual forms judgments from a partial and potentially distorted view of the surrounding network. We study whether graph…
Rethinking Sampling Strategy in Link Prediction
Yilin Bi, Zhenyu Deng, Xinshan Jiao +1
Many real-world networks are incomplete, making link prediction a fundamental challenge in network science. To train parameters and evaluate algorithms, observed links are usually…
Quantifying and Mitigating Self-Preference Bias of LLM Judges
Jinming Yang, Zheng Hu, Chuxian Qiu +3
LLM-as-a-Judge has become a dominant approach in automated evaluation systems, playing critical roles in model alignment, leaderboard construction, quality control, and so on. Howe…
Impacts of Data Splitting Strategies on Parameterized Link Prediction Algorithms
Xinshan Jiao, Yuxin Luo, Yilin Bi +1
Link prediction is a fundamental problem in network science, aiming to infer potential or missing links based on observed network structures. With the increasing adoption of parame…
Performances and Correlations of Centrality Measures in Complex Networks
Yilin Bi, Xinshan Jiao, Tao Zhou
Numerous centrality measures have been proposed to evaluate the importance of nodes in networks, yet comparative analyses of these measures remain limited. Based on 80 real-world n…
