摘要:

机器学习(ML)模型越来越多地用于辅助高风险行业的决策,这要求具备可解释性以促进信任。反事实解释(CEs)非常适合这一目标,因为它们能够说明输入数据的变化如何可能导致不同结果,从而提供对 ML 模型预测的洞察。然而,要让 CEs 发挥其解释潜力,在被解释场景发生轻微变化时确保其鲁棒性仍然存在重大挑战。尽管 CEs 的鲁棒性已被广泛认为是一项基本要求,但标准化工具和基准的缺乏阻碍了对鲁棒 CE 生成方法进行全面、有效的比较。本文提出 RobustX,这是一个开源 Python 库,实现了一系列 CE 生成与评估方法,并重点关注鲁棒性属性。RobustX 为文献中的若干现有方法提供接口,使用户能够便捷访问最先进技术。该库还易于扩展,支持快速原型化新的鲁棒 CE 生成与评估方法。

英文摘要:

The increasing use of Machine Learning (ML) models to aid decision-making in high-stakes industries demands explainability to facilitate trust. Counterfactual Explanations (CEs) are ideally suited for this, as they can offer insights into the predictions of an ML model by illustrating how changes in its input data may lead to different outcomes. However, for CEs to realise their explanatory potential, significant challenges remain in ensuring their robustness under slight changes in the scenario being explained. Despite the widespread recognition of CEs' robustness as a fundamental requirement, a lack of standardised tools and benchmarks hinders a comprehensive and effective comparison of robust CE generation methods. In this paper, we introduce RobustX, an open-source Python library implementing a collection of CE generation and evaluation methods, with a focus on the robustness property. RobustX provides interfaces to several existing methods from the literature, enabling streamlined access to state-of-the-art techniques. The library is also easily extensible, allowing fast prototyping of novel robust CE generation and evaluation methods.
