probly.evaluation.ood.out_of_distribution_detection_fnr_at_x_tpr¶

probly.evaluation.ood.out_of_distribution_detection_fnr_at_x_tpr(in_distribution: ndarray, out_distribution: ndarray, tpr_target: float = 0.95) → float[source]¶

Perform out-of-distribution detection using false negative rate at a given true positive rate.

If no thresholds are specified, the default tpr_target is 0.95.

Parameters:

in_distribution – In-distribution prediction functionals.
out_distribution – Out-of-distribution prediction functionals.
tpr_target – Target TPR value in (0, 1].

Returns:

False negative rate at the first threshold where TPR >= tpr_target.
