Explaining the Explainers in Graph Neural Networks: a Comparative Study

2 code implementations27 Oct 2022 Antonio Longa, Steve Azzolin, Gabriele Santin, Giulia Cencetti, Pietro Liò, Bruno Lepri, Andrea Passerini

Following a fast initial breakthrough in graph based learning, Graph Neural Networks (GNNs) have reached a widespread application in many science and engineering fields, prompting the need for methods to understand their decision process.

Global Explainability of GNNs via Logic Combination of Learned Concepts

1 code implementation13 Oct 2022 Steve Azzolin, Antonio Longa, Pietro Barbiero, Pietro Liò, Andrea Passerini

While instance-level explanation of GNN is a well-studied problem with plenty of approaches being developed, providing a global explanation for the behaviour of a GNN is much less explored, despite its potential in interpretability and debugging.
