Revisiting and Benchmarking Graph Autoencoders: A Contrastive Learning Perspective

1 code implementation14 Oct 2024 Jintang Li, Ruofan Wu, Yuchang Zhu, Huizhe Zhang, Xinzhou Jin, Guibin Zhang, Zulun Zhu, Zibin Zheng, Liang Chen

Graph autoencoders (GAEs) are self-supervised learning models that can learn meaningful representations of graph-structured data by reconstructing the input graph from a low-dimensional latent space.

One Fits All: Learning Fair Graph Neural Networks for Various Sensitive Attributes

1 code implementation19 Jun 2024 Yuchang Zhu, Jintang Li, Yatao Bian, Zibin Zheng, Liang Chen

Accordingly, we propose a graph fairness framework based on invariant learning, namely FairINV, which enables the training of fair GNNs to accommodate various sensitive attributes within a single training session.

Fair Graph Representation Learning via Sensitive Attribute Disentanglement

1 code implementation11 May 2024 Yuchang Zhu, Jintang Li, Zibin Zheng, Liang Chen

In particular, the objective of group fairness is to ensure that the decisions made by GNNs are independent of the sensitive attribute.

The Devil is in the Data: Learning Fair Graph Neural Networks via Partial Knowledge Distillation

1 code implementation29 Nov 2023 Yuchang Zhu, Jintang Li, Liang Chen, Zibin Zheng

Experiments on several benchmark datasets demonstrate that FairGKD, which does not require access to demographic information, significantly improves the fairness of GNNs by a large margin while maintaining their utility.

Hetero$^2$Net: Heterophily-aware Representation Learning on Heterogenerous Graphs

no code implementations18 Oct 2023 Jintang Li, Zheng Wei, Jiawang Dan, Jing Zhou, Yuchang Zhu, Ruofan Wu, Baokun Wang, Zhang Zhen, Changhua Meng, Hong Jin, Zibin Zheng, Liang Chen

Through in-depth investigations on several real-world heterogeneous graphs exhibiting varying levels of heterophily, we have observed that heterogeneous graph neural networks (HGNNs), which inherit many mechanisms from GNNs designed for homogeneous graphs, fail to generalize to heterogeneous graphs with heterophily or low level of homophily.

Oversmoothing: A Nightmare for Graph Contrastive Learning?

1 code implementation3 Jun 2023 Jintang Li, Wangbin Sun, Ruofan Wu, Yuchang Zhu, Liang Chen, Zibin Zheng

Oversmoothing is a common phenomenon observed in graph neural networks (GNNs), in which an increase in the network depth leads to a deterioration in their performance.
