Evaluation¶
Evaluation protocol for detector studies.
The package holds the pieces a published detector number is built from:
group holdout that keeps every instance of a group on one side of the
split (group_holdout, GroupSplit, GroupLeakage), ranking
metrics that report a one-class fold as a refusal (ranking_metrics),
the clock control that is published beside every detector
(clock_control), and the worst-baseline alarm rule with the
false-alarm floor it carries (worst_baseline_threshold, fires,
far_floor, over_floor), and the conformal test martingale alarm
with its record-level false-alarm bound (conformal_p_values,
power_martingale, mixture_martingale, martingale_alarm).
| Name | Summary |
|---|---|
tsdive.eval.clock_control |
Score every window by how far into its own record it sits. |
tsdive.eval.conformal_p_values |
Conformal p-value of each stream score against its pool, in stream order. |
tsdive.eval.far_floor |
False-alarm rate of a score that reads nothing, at k baseline windows. |
tsdive.eval.fires |
True when score is strictly above threshold. |
tsdive.eval.group_holdout |
Assign whole groups to n_folds folds, balancing strata. |
tsdive.eval.martingale_alarm |
First index where the log martingale reaches log(1 / delta), else None. |
tsdive.eval.mixture_martingale |
Natural log of the mean over epsilons of the power martingales. |
tsdive.eval.over_floor |
How far a measured false-alarm rate sits above far_floor(k_baseline). |
tsdive.eval.power_martingale |
Natural log of the power martingale prod(epsilon * p ** (epsilon - 1)). |
tsdive.eval.ranking_metrics |
Score a fold: ROC-AUC, PR-AUC and precision at a recall floor. |
tsdive.eval.worst_baseline_threshold |
The alarm threshold: the largest score the tool gave a baseline window. |
tsdive.eval.GroupLeakage |
A holdout group was found on both sides of a split. |
tsdive.eval.GroupSplit |
A k-fold split in which every group sits entirely inside one fold. |
tsdive.eval.RankingMetrics |
Threshold-free metrics of a detector's scores against binary labels. |
