Update on ORAC-NT pipeline — Phase F results
Following the earlier FAR discussion, I’ve completed
validation of a morphology scoring layer on GWTC-3.
654 events processed. RF classifier (BBH vs NSBH):
- CV AUC = 0.893 ± 0.098 (5-fold)
- LOO: 17/17 NSBH correctly ranked
- Permutation p = 0.005 (N=10,000)
Score correlates with SNR (ρ=-0.74) and distance
(ρ=+0.82) — consistent with detectability-driven
morphology differences.
