The Relationships Among Several Attribute Reduction Methods of Formal Context
摘要
Abstract
The notions of granular consistent set and granular reduction in the formal context with respect to attribute oriented con-cept lattice are proposed in this paper. The judgment theorem for granular consistent set is provided and the granular reduction method is presented by using discernible attributes between objects. Furthermore, the relationships among granular reduction, attribute oriented granular reduction and classification reduction were investigated. It is shown that the attribute oriented granular consistent sets are clas-sification consistent sets. An example was presented to illustrate the related reduction methods.关键词
