PAC-Bayesian Adversarially Robust Generalization for Message Passing Graph Neural Networks: A Sensitivity Analysis
arXiv:2606.06293v1 Announce Type: new Abstract: Whilst the vulnerability of graph neural networks (GNNs) to adversarial attacks poses a critical threat to graph representation learning, the understanding of the robust generalization behavior remains a fundamental challenge in the adversarial setting. Recently, PAC-Bayesian margin-based generalization analysis substantially advances this line of research by providing a flexible and data-dependent analytical framework. However, existing robust analyses often rely on isotropic Gaussian posteriors and control weight perturbations in the full param
The increasing deployment of GNNs in critical applications makes their robustness to adversarial attacks a pressing concern, driving new research into robust generalization.
Ensuring the reliable and secure operation of AI systems, particularly Graph Neural Networks (GNNs), is crucial for their adoption in sensitive domains such as finance, healthcare, and infrastructure.
New theoretical frameworks are emerging to better understand and quantify the robust generalization capabilities of GNNs, potentially leading to more resilient AI models.
