Shortcuts and Identifiability in Concept-based Models from a Neuro-Symbolic Lens

NeurIPS 2025poster

Concept-based Models are neural networks that learn a concept extractor to map inputs to high-level concepts and an inference layer to translate these into predictions. Ensuring these modules produce interpretable concepts and behave reliably in out-of-distribution is crucial, yet the conditions for…

A Neuro-Symbolic Benchmark Suite for Concept Quality and Reasoning Shortcuts

NeurIPS 2024poster

The advent of powerful neural classifiers has increased interest in problems that require both learning and reasoning. These problems are critical for understanding important properties of models, such as trustworthiness, generalization, interpretability, and compliance to safety and structural cons…

BEARS Make Neuro-Symbolic Models Aware of their Reasoning Shortcuts

UAI 2024poster

Neuro-Symbolic (NeSy) predictors that conform to symbolic knowledge {–} encoding, e.g., safety constraints {–} can be affected by Reasoning Shortcuts (RSs): They learn concepts consistent with the symbolic knowledge by exploiting unintended semantics. RSs compromise reliability and generalization an…
