摘要:

机器学习或人工智能算法由于其模仿和放大社会中现有偏见的倾向,近年来受到了相当多的关注。这导致了一个利基,但越来越多的工作,确定并试图修复这些偏见。使这些算法更公平的第一步是设计衡量不公平性的指标。这一领域的大多数现有工作要么涉及公平的二元观点(受保护群体与未受保护群体),要么涉及政治定义的类别(种族或性别)。这种分类忽略了交叉性的重要细微差别-在将不同类别的成员组合在一起的亚组中,偏见往往会被放大,特别是如果这样一个亚组在历史机会平台中的代表性特别不足。在本文中,我们讨论了为什么公平性指标需要在交叉性的镜头下看,确定现有的工作在交叉公平性,提出了一个简单的最坏情况下的比较方法,以扩大现有的组公平性指标的定义,将交叉性,并最终得出结论的社会,法律和政治框架,以处理交叉公平在现代背景下。

英文摘要:

Machine Learning or Artificial Intelligence algorithms have gained considerable scrutiny in recent times owing to their propensity towards imitating and amplifying existing prejudices in society. This has led to a niche but growing body of work that identifies and attempts to fix these biases. A first step towards making these algorithms more fair is designing metrics that measure unfairness. Most existing work in this field deals with either a binary view of fairness (protected vs. unprotected groups) or politically defined categories (race or gender). Such categorization misses the important nuance of intersectionality - biases can often be amplified in subgroups that combine membership from different categories, especially if such a subgroup is particularly underrepresented in historical platforms of opportunity. In this paper, we discuss why fairness metrics need to be looked at under the lens of intersectionality, identify existing work in intersectional fairness, suggest a simple worst case comparison method to expand the definitions of existing group fairness metrics to incorporate intersectionality, and finally conclude with the social, legal and political framework to handle intersectional fairness in the modern context.
