Bias AUC

Description

Suite of threshold-agnostic metrics that provide a nuanced view of this unintended bias, by considering the various ways that a classifier’s score distribution can vary across designated groups.

The following are computed:

Subgroup AUC
BPSN (Background Positive, Subgroup Negative) AUC
BNSP (Background Negative, Subgroup Positive) AUC
GMB (Generalized Mean of Bias) AUC

How to use

from evaluate import load

target = [['Islam'],
 ['Sexuality'],
 ['Sexuality'],
 ['Islam']]

label = [0, 0, 1, 1]

output = [[0.44452348351478577, 0.5554765462875366],
 [0.4341845214366913, 0.5658154487609863],

 [0.3840397894382477, 0.6159601807594299]]

metric = load('Intel/bias_auc')

metric.add_batch(target=target,
                 label=label,
                 output=output)
