摘要
讨论了以证据形式表达的多源信息聚类问题,并根据证据之间的冲突程度提出了证据聚类准则.在此基础上,还研究了证据在各类之间转移时引起聚类状态改变的情况,并根据Dempster组合规则推导出了证据与各类之间的隶属关系,为寻找证据聚类方法提供了理论基础.
A problem of clustering multl-source information expressed by evidence is investigated. According to conflict among evidences, a role is built for evidence clustering. Based on it, this paper studies the changes Caused by shifting evidence among different clusters. The membership relation between evidences and clusters is derived by Dempster combination rule, which lays the theoretical basis for evidence clustering methods.
