论文摘要
Dwork等人提出的个人公平性是一种公平措施，应该防止在亚组水平上对个体的不公平待遇，并克服了群体公平措施容易受到操纵或出现的问题的问题。本文的目的是探索有可能在多大程度上摆脱个人公平本身的程度。可以证明，在预测分数的背景下，挑剔的个人公平性是可能的。还将争辩说，个人公平为某些特征空间和度量的选择提供了非常弱的公平概念。最后，将讨论如何通过制定公平概念来保留个人公平的一般思想，该概念使我们能够克服在此处和其他地方确定的个人公平性问题。
Individual fairness, proposed by Dwork et al., is a fairness measure that is supposed to prevent the unfair treatment of individuals on the subgroup level, and to overcome the problem that group fairness measures are susceptible to manipulation, or gerrymandering. The goal of the present paper is to explore the extent to which it is possible to gerrymander individual fairness itself. It will be proved that gerrymandering individual fairness in the context of predicting scores is possible. It will also be argued that individual fairness provides a very weak notion of fairness for some choices of feature space and metric. Finally, it will be discussed how the general idea of individual fairness may be preserved by formulating a notion of fairness that allows us to overcome some of the problems with individual fairness identified here and elsewhere.
