anomaly_operating_point — SPC anomaly_eval op

• 데이터 종류: signal × signal → table

• 호출: import fullseye as fs; fs.ledger.anomaly_operating_point(scores, labels, recall=0.95, confidence=0.95)(구현을 직접 호출하려면 import anomeval; anomeval.anomaly_operating_point(scores, labels, recall=0.95, confidence=0.95), 원장에서 가져오려면 opsspc.get("anomaly_operating_point"))

사용법

결함 재현율이 confidence 수준에서 recall 이상임을 보장할 수 있는 가장 높은 임계값을 고른다 (table).

> 아래 상세 설명은 원문입니다 —— 요약과 제목은 번역되어 있습니다.

scores (1-D, higher = more anomalous) and labels (1 / True = defective) are image scores of a held-out set that was NOT used to fit the detector. Detecting k of the n defective images, the exact one-sided Clopper–Pearson lower limit of the recall at level confidence is computed; the smallest k whose limit reaches recall fixes the threshold at the k-th highest defect score (>= rule: the highest threshold that still carries the guarantee, so the fewest false alarms). The guarantee holds for defects drawn like the held-out ones; it is a statement about a sample, not about every future defect. Returns threshold, recall_observed, recall_lower (the limit), detected, n_pos, n_neg, fpr (fraction of good images at or above the threshold), fpr_upper (its one-sided Clopper–Pearson upper limit at the same level) and n_required (the smallest number of defective images for which the guarantee is attainable at all:

ceil(ln(1 - confidence) / ln(recall))).

Raises ValueError when the guarantee is unattainable with so few defective images (n_pos < n_required): it never returns a threshold it cannot back. Also on empty / mismatched / non-finite input, non-binary labels, no good or no defective image, or recall / confidence outside (0, 1).
