FairTest



FairTest

FairTest enables developers or auditing entities to discover and test for unwarranted associations between an algorithm’s outputs and certain user subpopulations identified by protected features.

FairTest works by learning a special decision tree, that splits a user population into smaller subgroups in which the association between protected features and algorithm outputs is maximized. FairTest supports and makes use of a variety of different fairness metrics each appropriate in a particular situation. After finding these so-called contexts of association, FairTest uses statistical methods to assess their validity and strength. Finally, FairTest retains all statistically significant associations, ranks them by their strength, and reports them as association bugs to the user.
