Universal Link Predictor By In-Context Learning on Graphs

no code implementations12 Feb 2024 Kaiwen Dong, Haitao Mao, Zhichun Guo, Nitesh V. Chawla

In this work, we introduce the Universal Link Predictor (UniLP), a novel model that combines the generalizability of heuristic approaches with the pattern learning capabilities of parametric models.

Pure Message Passing Can Estimate Common Neighbor for Link Prediction

1 code implementation2 Sep 2023 Kaiwen Dong, Zhichun Guo, Nitesh V. Chawla

This discrepancy stems from a fundamental limitation: while MPNNs excel in node-level representation, they stumble with encoding the joint structural features essential to link prediction, like CN.

FakeEdge: Alleviate Dataset Shift in Link Prediction

1 code implementation29 Nov 2022 Kaiwen Dong, Yijun Tian, Zhichun Guo, Yang Yang, Nitesh V. Chawla

In this paper, we first identify the dataset shift problem in the link prediction task and provide theoretical analyses on how existing link prediction methods are vulnerable to it.
