finding binding
boundThe set of 29 induction heads in gpt2-medium (top heads L9H9, L11H1, L18H5, L7H2, L6H1) is causally necessary for in-context repetition: group mean-ablation raises repeat-prediction loss by Delta=8.586 nats (per-seed deltas 8.53, 8.61, 8.84, 8.55, 8.41, all positive), versus ~0 for a control head set.
