摘要:

意识到数据中嵌入的历史歧视并考虑公平性措施以减少整个预测建模流程中的偏差至关重要。考虑到文献中定义的各种公平性概念,调查指标之间的相关性和相互作用对于解决不公平性至关重要。从业者和数据科学家应该能够理解每个指标,并根据上下文、用例和法规检查它们对彼此的影响。探索用于这种检查的不同度量的组合空间是繁重的。为了减轻选择公平概念的负担,我们提出了一个框架,估计公平概念之间的相关性。因此,我们的框架确定了一组不同的和语义上不同的指标作为代表给定的上下文。我们提出了一个蒙特卡罗抽样技术计算的公平性指标之间的相关性间接和有效的扰动模型空间。使用估计的相关性,然后我们找到一个子集的代表性指标。本文提出了一种通用的方法,可以推广到任何任意一组公平性指标。我们展示了使用真实世界的基准数据集上的综合实验的建议的有效性。

英文摘要:

It is of critical importance to be aware of the historical discrimination embedded in the data and to consider a fairness measure to reduce bias throughout the predictive modeling pipeline. Given various notions of fairness defined in the literature, investigating the correlation and interaction among metrics is vital for addressing unfairness. Practitioners and data scientists should be able to comprehend each metric and examine their impact on one another given the context, use case, and regulations. Exploring the combinatorial space of different metrics for such examination is burdensome. To alleviate the burden of selecting fairness notions for consideration, we propose a framework that estimates the correlation among fairness notions. Our framework consequently identifies a set of diverse and semantically distinct metrics as representative for a given context. We propose a Monte-Carlo sampling technique for computing the correlations between fairness metrics by indirect and efficient perturbation in the model space. Using the estimated correlations, we then find a subset of representative metrics. The paper proposes a generic method that can be generalized to any arbitrary set of fairness metrics. We showcase the validity of the proposal using comprehensive experiments on real-world benchmark datasets.
