Towards Robust Metrics for Concept Representation Evaluation

1 code implementation25 Jan 2023 Mateo Espinosa Zarlenga, Pietro Barbiero, Zohreh Shams, Dmitry Kazhdan, Umang Bhatt, Adrian Weller, Mateja Jamnik

In this paper, we show that such metrics are not appropriate for concept learning and propose novel metrics for evaluating the purity of concept representations in both approaches.

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.

Algorithmic Concept-based Explainable Reasoning

1 code implementation15 Jul 2021 Dobrik Georgiev, Pietro Barbiero, Dmitry Kazhdan, Petar Veličković, Pietro Liò

Recent research on graph neural network (GNN) models successfully applied GNNs to classical graph algorithms and combinatorial optimisation problems.

Failing Conceptually: Concept-Based Explanations of Dataset Shift

1 code implementation18 Apr 2021 Maleakhi A. Wijaya, Dmitry Kazhdan, Botty Dimanov, Mateja Jamnik

Using two case studies (dSprites and 3dshapes), we demonstrate how CBSD can accurately detect underlying concepts that are affected by shifts and achieve higher detection accuracy compared to state-of-the-art shift detection methods.
