Robust Graph Neural Networks via Unbiased Aggregation

no code implementations25 Nov 2023 Ruiqi Feng, Zhichao Hou, Tyler Derr, Xiaorui Liu

The adversarial robustness of Graph Neural Networks (GNNs) has been questioned due to the false sense of security uncovered by strong adaptive attacks despite the existence of numerous defenses.

Automated Polynomial Filter Learning for Graph Neural Networks

no code implementations16 Jul 2023 Wendi Yu, Zhichao Hou, Xiaorui Liu

Polynomial graph filters have been widely used as guiding principles in the design of Graph Neural Networks (GNNs).

Can Directed Graph Neural Networks be Adversarially Robust?

no code implementations3 Jun 2023 Zhichao Hou, Xitong Zhang, Wei Wang, Charu C. Aggarwal, Xiaorui Liu

This work presents the first investigation into the robustness of GNNs in the context of directed graphs, aiming to harness the profound trust implications offered by directed graphs to bolster the robustness and resilience of GNNs.
