finding binding
boundThe set of 15 induction heads in gpt2 (top heads L7H10, L5H1, L5H5, L6H9, L7H2) is causally necessary for in-context repetition: group mean-ablation raises repeat-prediction loss by Delta=8.354 nats (per-seed deltas 8.56, 8.40, 8.96, 8.13, 7.72, all positive), versus ~0 for a control head set.
