摘要:

我们社会中存在的系统性歧视性偏见影响着数据的收集和存储方式,变量的定义方式,以及科学发现作为政策付诸实践的方式。应用于这些数据的自动决策程序和学习算法可能会使我们社会中现有的不公正或不公平现象永久化。在本文中,我们考虑如何做出最优但公平的决策,通过纠正决策和结果对敏感特征(例如,对应于性别、种族、残疾或其他受保护属性的变量)。我们使用因果推理和约束优化的方法来学习最优策略,以解决在敏感环境中影响数据分析的多种潜在偏见,扩展了(Nabi和Shpitser 2018)的方法。我们的建议配备了理论上的保证,所选择的公平的政策将导致一个联合分布的新的情况下,满足给定的公平性约束。我们用合成数据和真实的刑事司法数据来说明我们的方法。

英文摘要:

Systematic discriminatory biases present in our society influence the way data is collected and stored, the way variables are defined, and the way scientific findings are put into practice as policy. Automated decision procedures and learning algorithms applied to such data may serve to perpetuate existing injustice or unfairness in our society. In this paper, we consider how to make optimal but fair decisions, which "break the cycle of injustice" by correcting for the unfair dependence of both decisions and outcomes on sensitive features (e.g., variables that correspond to gender, race, disability, or other protected attributes). We use methods from causal inference and constrained optimization to learn optimal policies in a way that addresses multiple potential biases which afflict data analysis in sensitive contexts, extending the approach of (Nabi and Shpitser 2018). Our proposal comes equipped with the theoretical guarantee that the chosen fair policy will induce a joint distribution for new instances that satisfies given fairness constraints. We illustrate our approach with both synthetic data and real criminal justice data.
