AI总结:

本文提出了一种高效探索规则集模型Rashomon集的方法,支持穷举或非穷举搜索,避免了冗余枚举,并通过大量实验验证了其有效性。

摘要:

如今,随着越来越复杂的预测模型被开发出来,简单的规则集仍然是获取可解释预测和驱动高风险决策的关键工具。然而,单一规则集只能提供对学习任务的部分表示。可解释机器学习中的一种新兴范式旨在探索所有表现出接近最优性能模型的Rashomon集。现有的Rashomon集探索工作集中于对特定类别的模型进行穷举搜索,这可能是一项计算上具有挑战性的任务。另一方面,穷举枚举会导致通常不必要的冗余,而代表性样本或对Rashomon集大小的估计对于许多应用来说已经足够。在这项工作中,我们首次提出了高效的方法,以通过或无需穷举搜索来探索规则集模型的Rashomon集。大量实验证明了所提出方法在各种场景中的有效性。

英文摘要:

Today, as increasingly complex predictive models are developed, simple rule sets remain a crucial tool to obtain interpretable predictions and drive high-stakes decision making. However, a single rule set provides a partial representation of a learning task. An emerging paradigm in interpretable machine learning aims at exploring the Rashomon set of all models exhibiting near-optimal performance. Existing work on Rashomon-set exploration focuses on exhaustive search of the Rashomon set for particular classes of models, which can be a computationally challenging task. On the other hand, exhaustive enumeration leads to redundancy that often is not necessary, and a representative sample or an estimate of the size of the Rashomon set is sufficient for many applications. In this work, we propose, for the first time, efficient methods to explore the Rashomon set of rule set models with or without exhaustive search. Extensive experiments demonstrate the effectiveness of the proposed methods in a variety of scenarios.
