Graph Agent Network: Empowering Nodes with Inference Capabilities for Adversarial Resilience

2025 · Proceedings of the AAAI Conference on Artificial Intelligence

End-to-end training with global optimization have popularized graph neural networks (GNNs) for node classification, yet inadvertently introduced vulnerabilities to adversarial edge-perturbing attacks. Adversaries can exploit the inherent opened interfaces of GNNs' input and output, perturbing …
