复合覆盖粗糙集模型及其应用
Composite covering rough sets model and its application
摘要
Abstract
Because the classical covering rough sets can only apply to single data type in the covering domain, composite covering rough sets are presented. Firstly, based on the study of the neighborhood covering rough sets, the set-valued cov-ering rough sets and the interval-valued covering rough sets, composite covering rough sets are presented by establishing a variety of coverage relations, includes neighborhood covering relation, set-valued covering relation, the interval-valued covering relation, which are under the composite data model. The relevant concepts and properties are presented. Sec-ondly, the model are applied to the domain covering problem of a variety of data types, for example symbol data, interval-valued data, set-valued data, number data etc. Finally, an example is given to illustrate the application of the model in com-posite information system for further deep understanding of the related concepts in composite covering rough sets.关键词
