对易出错结果的公平推断

Fair inference on error-prone outcomes

摘要:

监督学习中的公平推理是一个重要而活跃的研究领域,在预测地面真实目标时,产生了一系列有用的方法来评估和解释公平性标准。然而,如在最近的工作中所示,当目标标签容易出错时,潜在的预测不公平性可能由测量误差引起。在本文中,我们表明,当使用一个容易出错的代理目标,现有的方法来评估和校准公平性标准不扩展到真正的目标变量的兴趣。为了解决这个问题,我们提出了一个框架,从现有的两个文献的组合:公平ML方法,如那些在反事实的公平性文献,一方面,另一方面,在统计文献中发现的测量模型。我们讨论这些方法和它们的连接导致我们的框架。在一个医疗决策问题中,我们发现使用潜变量模型来解释测量误差消除了先前检测到的不公平。

英文摘要:

Fair inference in supervised learning is an important and active area of research, yielding a range of useful methods to assess and account for fairness criteria when predicting ground truth targets. As shown in recent work, however, when target labels are error-prone, potential prediction unfairness can arise from measurement error. In this paper, we show that, when an error-prone proxy target is used, existing methods to assess and calibrate fairness criteria do not extend to the true target variable of interest. To remedy this problem, we suggest a framework resulting from the combination of two existing literatures: fair ML methods, such as those found in the counterfactual fairness literature on the one hand, and, on the other, measurement models found in the statistical literature. We discuss these approaches and their connection resulting in our framework. In a healthcare decision problem, we find that using a latent variable model to account for measurement error removes the unfairness detected previously.
