arXiv:2512.05038v2 Announce Type: replace Abstract: Concept vectors aim to enhance model interpretability by linking internal representations with human-understandable semantics, but their practical utility is often limited by noisy and inconsistent activations. In this work, we uncover the SuperActivator Mechanism: a transformer dynamic that amplifies concept activation gaps, concentrating the most reliable concept evidence into a small set of high-activation tokens. To develop a theoretical understanding of this mechanism, we prove that concept-aligned attention heads multiplicatively amplif
Ongoing research into AI interpretability and efficiency is driving new discoveries about transformer mechanisms.
Understanding the SuperActivator Mechanism could lead to more robust, interpretable, and efficient AI models, accelerating their adoption and capability.
This discovery provides a foundational understanding of how transformers process and prioritize information, potentially enabling more targeted and effective AI development.
