三支决策视角下多分类研究综述及展望

Review and Prospect of Multi-classification Research From the Perspective of Threeway Decisions

三支决策用于处理复杂的、不确定问题,将实际问题通过三元思维整体划分为分离且有内在联系的三个部分,针对不同部分采取不同行动从而指导最终决策。传统三支决策解决二分类问题,数据信息海量增长二分类问题逐渐扩展,多分类得到广泛关注。从三支决策理论出发,介绍多分类三支决策理论研究,总结二者的理论及应用成果,展望其未来研究方向。

Three-way decisions are used to deal with complex and uncertain problems.The actual problems are divided into three separate and intrinsically related parts through ternary thinking,and different actions are taken for different parts to guide the final decision.The traditional three-way decision-making solves the problem of binary classification,and the massive growth of data information.The problem of binary classification gradually expands,and multi classification has been widely concerned.Starting from the three branch decision-making theory,this paper introduces the research of multi classification three-way decision-making theory,summarizes the theory and application results of the two,and looks forward to its future research direction.
