    "title": "Can Abstract Categories Be Represented by Shared Features in Concept Bottleneck Models?",
    "subtitle": null,
    "abstract": "Learning abstract concepts is a core component of human cognition, yet remains challenging for artificial intelligent. We present a computational model that investigates whether abstract categories can be acquired through shared perceptual features, using a Label-Free Concept Bottleneck Model (CBM) trained to induce basic-level concepts using shared features. Concepts are represented through intermediate concepts layer, enabling the model to form grounded representations of basic-level categories. To evaluate conceptual robustness beyond surface-level accuracy, we conduct a series of generalization and ablation experiments. These assess whether the model forms robust conceptual representations rather than merely mapping inputs to labels. Our results show that the CBM achieves high accuracy on a dataset comprising four basic-level classes and twelve subordinate Image-Net subclasses, while also yielding interpretable intermediate representations. This framework demonstrates that abstract categorization can emerge through feature based induction, and suggests a pathway for cognitive models of concept learning.",
