摘　　要：由于数据有复杂性、多样性和不确定性的特点,聚类通常存在不确定性,这种不确定性是指聚类结果的不一致性,从而影响分析的准确性,而通过三支决策方法构建不确定域,对不确定域进行延迟决策,能够带来一系列的优势。近些年来,这个研究热点涌现许多重要的工作。对聚类不确定的三支决策方法模型和研究方向进行介绍,按照三支聚类构建过程中遇到的问题进行总结。首先,给出三支聚类的表现形式。其次,分别阐述如何构建三支聚类的核心域和边界域,如何确定阈值,如何设计有效性指标,并介绍其中具有代表性的工作。最后,对聚类不确定的三支决策方法进行总结,并展望未来的研究方向。Due to the characteristic of complexity,diversity and uncertainty of data,clustering usually has uncertainty,which refers to the inconsistency of clustering results,thus affecting the accuracy of analysis.The Three-way Decision method can bring a series of advantages by constructing an uncertain domain and making delayed decision on the uncertain domain.In recent years,a lot of important work has emerged from this research hotspot.This paper introduces the model and the research direction of Three-way Decision method with clustering uncertainty,and summarizes the problems encountered in the construction process of Three-way Clustering.Firstly,the expression form of the Three-way Clustering is given.Secondly,the paper describes how to construct the core domain and boundary domain of the Three-way Clustering,how to determine the threshold value and how to design the validity index,respectively.It also introduces the representative work among them.Finally,the paper summarizes the Three-way Decision method of clustering uncertainty,and looks forward to the future research direction.
