摘要:

在许多应用领域-例如贷款、教育和在线零售商-当机器学习系统与动态变化的环境交互时,公平和公正问题就会出现,从而对个人和人口群体产生即时和长期影响。我们讨论因果有向无环图(DAG)作为一个统一的框架,最近的文献公平性,在这样的动态系统。我们表明,这种提法提供了几个新的调查方向的建模,因果关系的假设可以表达和操纵。我们强调在动态公平设置中计算干预量的重要性,并展示了因果假设如何使模拟(当环境动态已知时)和离线政策估计(当动态未知时)在组和个人层面上对短期和长期结果进行干预。

英文摘要:

In many application areas---lending, education, and online recommenders, for example---fairness and equity concerns emerge when a machine learning system interacts with a dynamically changing environment to produce both immediate and long-term effects for individuals and demographic groups. We discuss causal directed acyclic graphs (DAGs) as a unifying framework for the recent literature on fairness in such dynamical systems. We show that this formulation affords several new directions of inquiry to the modeler, where causal assumptions can be expressed and manipulated. We emphasize the importance of computing interventional quantities in the dynamical fairness setting, and show how causal assumptions enable simulation (when environment dynamics are known) and off-policy estimation (when dynamics are unknown) of intervention on short- and long-term outcomes, at both the group and individual levels.
