WebMar 3, 2024 · predictive parity does not impose any restrictions on the extent to which a model amplifies disparity. Calibration is more restrictive in this regard, but the common post-processing method of thresh-olding can amplify disparity to an arbitrary extent. Since equalized odds is incompatible with predictive parity or calibration [6, 8, 23], In classification problems, an algorithm learns a function to predict a discrete characteristic , the target variable, from known characteristics . We model as a discrete random variable which encodes some characteristics contained or implicitly encoded in that we consider as sensitive characteristics (gender, ethnicity, sexual orientation, etc.). We finally denote by the prediction of the classifier. Now let us define three main criteria to evaluate if a given classifier is fair, that is i…
