Many Circuits, One Mechanism: Input Variation and Evaluation Granularity in Circuit Discovery 事件

Many Circuits, One Mechanism: Input Variation and Evaluation Granularity in Circuit Discovery arXiv:2606.06267v1 Announce Type: new Abstract: Circuit discovery methods identify subgraphs that explain specific model behaviors, and structural differences between discovered circuits are commonly interpreted as evidence of distinct mechanisms. We test this assumption by varying input statistics while holding the task fixed, and show that the resulting structural differences exhibit apparent special
