arXiv:2606.03495v1 Announce Type: new Abstract: Heterogeneous graph neural networks (HGNNs) have demonstrated remarkable performance in modeling complex relational data, however their interpretability in high-stakes applications remains a critical challenge. Existing explanation methods suffer from two major limitations: on the one hand, the generated explanations fail to reflect the inherent semantic hierarchy of HGNNs, resulting in a lack of fidelity to the model's internal decision-making mechanism; on the other hand, feature explanations often rely on complex search or perturbation mechani
The increasing complexity and adoption of graph neural networks in critical applications demand better interpretability and explainability, which is a current frontier in AI research.
Improved interpretability for HGNNs addresses a key barrier to wider deployment of advanced AI in high-stakes environments, enhancing trust and reliability.
The development of more lightweight and semantically aligned explanation methods will make sophisticated AI models more understandable and auditable, potentially accelerating their adoption in sensitive sectors.
