finding binding
boundThe set of 5 induction heads in pythia-70m (top heads L3H6, L3H5, L3H1, L3H0, L4H7) is causally necessary for in-context repetition: group mean-ablation raises repeat-prediction loss by Delta=4.949 nats (per-seed deltas 4.03, 3.85, 5.22, 5.54, 6.11, all positive), versus ~0 for a control head set.
