Semifactual Explanations for GNN-based Classification: Formal Foundations, Complexity and Computation

IJCAI 2026

Graph Neural Networks (GNNs) have become increasingly central to several analysis tasks in various domains, ranging, e.g., from social networks to molecular analysis. Understanding the decision-making process of GNNs is a critical challenge in machine learning, particularly when post-hoc explanation

Even-if Explanations: Formal Foundations, Priorities and Complexity

AAAI 2025technical

Explainable AI has received significant attention in recent years. Machine learning models often operate as black boxes, lacking explainability and transparency while supporting decision-making processes. Local post-hoc explainability queries attempt to answer why individual inputs are classified i…
