Beyond Soft Masks: Hard-Perturbation Mixup Explainer for Robust GNN Explainability

Researchers propose HPME, a novel framework for explaining Graph Neural Network decisions using hard-perturbation mixup strategies instead of soft masks. The method addresses out-of-distribution issues in GNN explainability by extracting discrete subgraphs and employing structure-level replacement, achieving improved explanation fidelity across synthetic and real-world datasets.
