GCExplainer: Human-in-the-Loop Concept-based Explanations for Graph Neural Networks

no code implementations25 Jul 2021 Lucie Charlotte Magister, Dmitry Kazhdan, Vikash Singh, Pietro Liò

Motivated by the aim of providing global explanations, we adapt the well-known Automated Concept-based Explanation approach (Ghorbani et al., 2019) to GNN node and graph classification, and propose GCExplainer.

Quantum Graph Neural Networks

2 code implementations26 Sep 2019 Guillaume Verdon, Trevor McCourt, Enxhell Luzhnica, Vikash Singh, Stefan Leichenauer, Jack Hidary

We introduce Quantum Graph Neural Networks (QGNN), a new class of quantum neural network ansatze which are tailored to represent quantum processes which have a graph structure, and are particularly suitable to be executed on distributed quantum systems over a quantum network.
