Interpretable but Fragile? Robustness of Concept Bottlenecks under Geometric-Semantic Perturbations
Concept Bottleneck Models (CBMs) are designed to provide interpretable intermediate representations, yet how such bottlenecks affect robustness remains unclear, with existing studies reporting mixed and sometimes contradictory findings. We argue that these discrepancies arise from conflating different robustness notion …
