Exploring Task Unification in Graph Representation Learning via Generative Approach

no code implementations21 Mar 2024 Yulan Hu, Sheng Ouyang, Zhirui Yang, Ge Chen, Junchen Wan, Xiao Wang, Yong liu

Specifically, GA^2E proposes to use the subgraph as the meta-structure, which remains consistent across all graph tasks (ranging from node-, edge-, and graph-level to transfer learning) and all stages (both during training and inference).

VIGraph: Generative Self-supervised Learning for Class-Imbalanced Node Classification

no code implementations2 Nov 2023 Yulan Hu, Sheng Ouyang, Zhirui Yang, Yong liu

VIGraph strictly adheres to the concept of imbalance when constructing imbalanced graphs and innovatively leverages the variational inference (VI) ability of Variational GAE to generate nodes for minority classes.

Graph Ranking Contrastive Learning: A Extremely Simple yet Efficient Method

no code implementations23 Oct 2023 Yulan Hu, Sheng Ouyang, Jingyu Liu, Ge Chen, Zhirui Yang, Junchen Wan, Fuzheng Zhang, Zhongyuan Wang, Yong liu

Thus, we propose GraphRank, a simple yet efficient graph contrastive learning method that addresses the problem of false negative samples by redefining the concept of negative samples to a certain extent, thereby avoiding the issue of false negative samples.
