基于集对顺势相似关系的变精度粗糙集模型
Variable precision rough set model based on set pair homeopathic simi- lar relationship
摘要
Abstract
In order to deal with incomplete information system with noise data, ambiguity and other information, the thought and method of the set pair theory and variable precision rough set is used to construct a novel variable precision rough set model. To begin with, the advantages and limitations of these models previously established based on the set pair similarity relationship are compared, and then the set pair homeopathic similar relationship based on the threshold αconnection degree is defined, and then it is used to substitute the equivalence relationship of the variable precision rough set, so that a novel variable precision rough set model based on the set pair homeopathic similar relationship is established, and its properties are researched. Finally an example is used to verify the feasibility and effectiveness of the novel model.关键词
