论文摘要
反事实解释已在解释性方面进行了广泛的研究，并在公平，追索和模型理解方面出现了一系列依赖性方法。但是，与这些方法相关的主要缺点是它们无法提供本地或实例级别以外的解释。尽管有些作品涉及全球解释的概念，通常建议汇总局部解释，以确定全球属性，但很少有人提供可靠或可以计算可靠的框架。同时，从业人员要求更有效，更具交互性的解释性工具。我们借此机会调查了现有的全球方法，重点是实施和改善可行的追索摘要（ARES），这是唯一已知的全球反事实解释框架。
Counterfactual explanations have been widely studied in explainability, with a range of application dependent methods emerging in fairness, recourse and model understanding. However, the major shortcoming associated with these methods is their inability to provide explanations beyond the local or instance-level. While some works touch upon the notion of a global explanation, typically suggesting to aggregate masses of local explanations in the hope of ascertaining global properties, few provide frameworks that are either reliable or computationally tractable. Meanwhile, practitioners are requesting more efficient and interactive explainability tools. We take this opportunity to investigate existing global methods, with a focus on implementing and improving Actionable Recourse Summaries (AReS), the only known global counterfactual explanation framework for recourse.
