论文摘要
由于它们对社会决策产生至关重要的影响，因此AI算法不仅应该是准确的，而且应该是公平的。在公平性AI的各种算法中，通过最大程度地降低受特定公平限制的经验风险（例如，跨凝性）来学习预测模型。但是，为了避免计算困难，给定的公平限制被替代公平限制代替，因为0-1损失被凸面替代分类问题所取代。在本文中，我们调查了现有的替代公平性约束的有效性，并提出了一种称为幻灯片的新替代公平约束，该公平性在计算上是可行的，并且在渐近上有效，从而使学识渊博的模型无效地满足公平性约束并实现快速融合率。数值实验证实，幻灯片适用于各种基准数据集。
As they have a vital effect on social decision makings, AI algorithms should be not only accurate and but also fair. Among various algorithms for fairness AI, learning a prediction model by minimizing the empirical risk (e.g., cross-entropy) subject to a given fairness constraint has received much attention. To avoid computational difficulty, however, a given fairness constraint is replaced by a surrogate fairness constraint as the 0-1 loss is replaced by a convex surrogate loss for classification problems. In this paper, we investigate the validity of existing surrogate fairness constraints and propose a new surrogate fairness constraint called SLIDE, which is computationally feasible and asymptotically valid in the sense that the learned model satisfies the fairness constraint asymptotically and achieves a fast convergence rate. Numerical experiments confirm that the SLIDE works well for various benchmark datasets.
