Abstract
Data mining approaches for discrimination discovery unveil contexts of possible discrimination against protected-by-law groups by extracting classication rules from a dataset of historical decision records. Rules are ranked according to some legally-grounded contrast measure dened over a 4- fold contingency table, including risk dierence, risk ratio, odds ratio, and a few others. Due to time and cost con- straints, however, only the top-k ranked rules are taken into further consideration by an anti-discrimination analyst. In this paper, we study to what extent the sets of top-k ranked rules with respect to any two pairs of measures agreeFile | Dimensione | Formato | |
