摘　　要：随着人工智能(AI)技术的迅速发展,机器学习在材料研发与设计中发挥着越来越重要的作用。传统机器学习模型往往为“黑盒”模型,限制了科研人员对模型决策过程的理解和信任。而可解释机器学习(XML)可以揭示机器学习模型的内部机制,提供对模型决策过程的洞察。本文从可解释机器学习的基础知识出发,概述了可解释机器学习方法的发展历程和重要里程碑,以及可解释机器学习在人工智能领域的定位和需要遵守的F.A.S.T.原则;进一步介绍了模型内部结构可解释和外部评估模型可解释的2大类可解释机器学习方法及其在材料学中的应用案例。特别地,本团队提出的可解释符号回归和可视化机器学习方法将为材料研发与设计提供新的工具。最后,展望了可解释机器学习在材料学领域的潜在发展方向。With the rapid advancement of artificial intelligence(AI),machine learning is playing an increasingly important role in materials research,development,and design.Traditional machine learning models are often“black box”models that limit researchersunderstanding of a models decision-making and undermines their confidence in the process.Explainable machine learning(XML)can reveal the internal mechanisms of these models and provide insights into their decision-making processes.This study begins with the fundamentals of XML,outlines the development history and notable milestones of XML methods,and discusses the role of XML in AI,emphasizing the Fairness,Accountability,Simplicity,and Transparency(F.A.S.T.)principles that should be followed.Furthermore,this study introduces two major categories of XML methods—those that use model-intrinsic interpretability and those that use external model interpretability—along with their applications in materials science.Specifically,the symbolic regression of XML and visualized XML methods developed by our team offer new tools for materials research and design.Finally,potential directions for XML in the field of materials science are discussed.
