Scalable Evaluation and Neural Models for Compositional Generalization

Giacomo Camposampiero, Pietro Barbiero, Michael Hersche +2

Compositional generalization-a key open challenge in modern machine learning-requires models to predict unknown combinations of known concepts. However, assessing compositional gen…

Foundations of Interpretable Models

Pietro Barbiero, Mateo Espinosa Zarlenga, Alberto Termine +2

We argue that existing definitions of interpretability are not actionable in that they fail to inform users about general, sound, and robust interpretable model design. This makes…

Interpretable Hierarchical Concept Reasoning through Attention-Guided Graph Learning

David Debot, Pietro Barbiero, Gabriele Dominici +1

Concept-Based Models (CBMs) are a class of deep learning models that provide interpretability by explaining predictions through high-level concepts. These models first predict conc…

Towards Better Generalization and Interpretability in Unsupervised Concept-Based Models

Francesco De Santis, Philippe Bich, Gabriele Ciravegna +3

To increase the trustworthiness of deep neural networks, it is critical to improve the understanding of how they make decisions. This paper introduces a novel unsupervised concept-…

Avoiding Leakage Poisoning: Concept Interventions Under Distribution Shifts

Mateo Espinosa Zarlenga, Gabriele Dominici, Pietro Barbiero +2

In this paper, we investigate how concept-based models (CMs) respond to out-of-distribution (OOD) inputs. CMs are interpretable neural architectures that first predict a set of hig…

Deferring Concept Bottleneck Models: Learning to Defer Interventions to Inaccurate Experts

Andrea Pugnana, Riccardo Massidda, Francesco Giannini +6

Concept Bottleneck Models (CBMs) are machine learning models that improve interpretability by grounding their predictions on human-understandable concepts, allowing for targeted in…
