arXiv:2605.23239v1 Announce Type: new Abstract: Defending Graph Neural Networks (GNNs) against adversarial attacks requires balancing accuracy and robustness, a trade-off often mishandled by traditional methods like adversarial training that intertwine these conflicting objectives within a single classifier. To overcome this limitation, we propose a self-supervised adversarial purification framework. We separate robustness from the classifier by introducing a dedicated purifier, which cleanses the input data before classification. In contrast to prior adversarial purification methods, we propo
The increasing deployment of GNNs in critical applications makes their vulnerability to adversarial attacks a pressing concern that requires immediate solutions.
Ensuring the robustness and reliability of AI systems, particularly Graph Neural Networks, is crucial for their trustworthy integration into sensitive domains like finance, healthcare, and defence.
This research introduces a novel self-supervised adversarial purification framework that separates robustness from the classifier, offering a new pathway to more resilient GNNs.
