论文摘要
我们提出了一个灵活的框架,用于学习预测模型,该模型大致满足公平的均衡概念。这是通过引入严格量化违反该标准的一般差异功能来实现的。这种可区分的功能用作将模型参数驱动到均衡赔率的惩罚。为了严格评估合适的模型,我们开发了正式的假设检验,以检测预测规则是否违反了该属性,这是文献中的第一个测试。模型拟合和假设测试都通过结构来遵守均衡的几率。我们证明了所提出的框架在回归和多类分类问题中的适用性和有效性,从而报告了对最新方法的性能提高。最后,我们展示了如何合并公平的不确定性量化技术 - 对于所研究的每个组而言,无偏见 - 以准确的术语传达数据分析的结果。
We present a flexible framework for learning predictive models that approximately satisfy the equalized odds notion of fairness. This is achieved by introducing a general discrepancy functional that rigorously quantifies violations of this criterion. This differentiable functional is used as a penalty driving the model parameters towards equalized odds. To rigorously evaluate fitted models, we develop a formal hypothesis test to detect whether a prediction rule violates this property, the first such test in the literature. Both the model fitting and hypothesis testing leverage a resampled version of the sensitive attribute obeying equalized odds, by construction. We demonstrate the applicability and validity of the proposed framework both in regression and multi-class classification problems, reporting improved performance over state-of-the-art methods. Lastly, we show how to incorporate techniques for equitable uncertainty quantification---unbiased for each group under study---to communicate the results of the data analysis in exact terms.
