GNNX-BENCH: Unraveling the Utility of Perturbation-Based GNN Explainers through Benchmarking Study at ICLR 2024


Concetti Chiave
Perturbation-based explainability methods for GNNs are systematically evaluated and compared, revealing insights on efficacy, stability, and feasibility.
Sintesi

This content discusses a benchmarking study on perturbation-based explainability methods for Graph Neural Networks (GNNs). The study aims to evaluate and compare various explainability techniques, focusing on factual and counterfactual reasoning. Key findings include the identification of Pareto-optimal methods with superior efficacy and stability in the presence of noise. However, all algorithms face stability issues when dealing with noisy data. The study also highlights the limitations of current counterfactual explainers in providing feasible recourses due to violations of domain-specific constraints.

Statistiche
数多くの説明可能性手法が提案されている。 提案されたアルゴリズムには実証評価が含まれている。 現在のカウンターファクトリー説明者は、ドメイン固有の考慮事項による制約違反のため、実行可能な手段を提供することがしばしば失敗する。
