摘要:

越来越多的人工智能和机器学习模型的应用带来了不公平行为的潜在风险,根据最近的法规,已经引起了研究界的关注。一些研究人员专注于寻求新的公平定义或开发方法来识别有偏见的预测。然而,没有人试图利用反事实空间来达到这一目的。在这个方向上,在这项工作中提出的方法,旨在揭示不公平的模型行为,使用反事实推理的情况下,在无意识设置的公平。定义了机会平等的反事实版本--反事实公平机会,并引入了两种新的度量方法来分析反事实样本中的敏感信息。在三个不同数据集上的实验结果显示了我们的方法和指标的有效性,揭示了经典机器学习和去偏置模型的不公平行为。

英文摘要:

The increasing application of Artificial Intelligence and Machine Learning models poses potential risks of unfair behavior and, in light of recent regulations, has attracted the attention of the research community. Several researchers focused on seeking new fairness definitions or developing approaches to identify biased predictions. However, none try to exploit the counterfactual space to this aim. In that direction, the methodology proposed in this work aims to unveil unfair model behaviors using counterfactual reasoning in the case of fairness under unawareness setting. A counterfactual version of equal opportunity named counterfactual fair opportunity is defined and two novel metrics that analyze the sensitive information of counterfactual samples are introduced. Experimental results on three different datasets show the efficacy of our methodologies and our metrics, disclosing the unfair behavior of classic machine learning and debiasing models.
