Attribute reduction of set-valued information system based on restriction tolerance relation
摘要
Abstract
This paper is devoted to the discussion of attribute reduction of set-valued information system based on symmetry restriction tolerance relation. The characteristic of similar level core attribute is introduced. The example shows that this algorithm can obtain the relative reduction of set-valued information system.关键词
