可解释机器学习致力于提供决策过程对人类透明的模型。近年来基于规则的方法(如表达性强的布尔公式,BoolXAI)能忠实且紧凑地表示模型行为。然而,对非技术利益相关者而言,实际挑战仍存在:(i) 选择语义上合理的关键特征;(ii) 将形式化的逻辑规则转化为易于理解的解释。本文提出 BoolXLLM,一个将大语言模型(LLM)融入布尔规则学习端到端流程的混合框架。我们在三个关键阶段引入 LLM:(1) 特征选择,由 LLM 指导识别领域相关的变量;(2) 阈值推荐,由 LLM 提出对数值特征具有语义意义的离散化策略;(3) 规则压缩与解释,将布尔规则转化为全局和局部层面的自然语言说明。该集成方式实现了形式化、准确的解释与人类可理解叙事之间的桥梁,构建了一个既理论扎实又对非专家友好的可解释 AI 系统。初步实证结果表明,大模型辅助的流程在保持竞争力预测性能的同时提升了可解释性。本工作凸显了符号推理与语言模型结合在以人为本可解释性方面的潜力。

原文摘要 · Abstract (English)

Interpretable machine learning aims to provide transparent models whose decision-making processes can be readily understood by humans. Recent advances in rule-based approaches, such as expressive Boolean formulas (BoolXAI), offer faithful and compact representations of model behavior. However, for non-technical stakeholders, main challenges remain in practice: (i) selecting semantically meaningful features and (ii) translating formal logical rules into accessible explanations. In this work, we propose BoolXLLM , as a hybrid framework that integrates Large Language Models (LLMs) into the end-to-end pipeline of Boolean rule learning. We augment BoolXAI , an expressive Boolean rule-based classifier, with LLMs at three critical stages: (1) feature selection, where LLMs guide the identification of domain-relevant variables; (2) threshold recommendation, where LLMs propose semantically meaningful discretization strategies for numerical features; and (3) rule compression and interpretation, where Boolean rules are translated into natural language explanations at both global and local levels. This integration bridges formal, faithful explanations with human-understandable narratives. This allows build an explainable AI system that is both theoretically grounded and accessible to non-experts. Early empirical results demonstrate that LLM-assisted pipelines improve interpretability while maintaining competitive predictive performance. Our work highlights the promise of combining symbolic reasoning with language-based models for human-centered explainability.
