arXiv:2602.09258v2 Announce Type: replace Abstract: Deployed graph neural networks (GNNs) are frozen at deployment yet must fit clean data, generalize under distribution shifts, and remain stable to perturbations. We show that static inference induces a fundamental tradeoff: improving stability requires reducing reliance on shift-sensitive features, leaving an irreducible worst-case generalization floor. Instance-conditional routing can break this ceiling, but is fragile because shifts can mislead routing and perturbations can make routing fluctuate. We capture these effects via two decomposit
This research addresses fundamental challenges in deploying AI, particularly GNNs, right as their real-world application is expanding beyond controlled environments into dynamic and unpredictable operational settings.
Improving the stability and generalization of GNNs in real-world scenarios is critical for the reliable deployment of advanced AI systems, impacting industries from logistics to national security.
The proposed technical advancements in GNNs via 'Tokenized Mixture of Experts' could lead to more robust and adaptable AI, potentially accelerating their integration into critical infrastructure.
