决策表中基于对象的μ-约简方法研究
Research on μ-Reduction Method for Objects in Decision Tables
摘要
Abstract
This paper studies the μ- reduction for the objects in inconsistent decision tables, introduces some properties and the equivalent definition of μ- reduction, obtains the judgment theorem and corresponding identification matrix and formula with respect to the μ-reduction, and proposes new approaches to knowledge reductions in inconsistent information systems. Compared with the overall reduction for a decision table, the reduction for the objects in the decision table not only can get more concise knowledge, but also has good application value in real life. In addition, this method is also suitable for the consistent information systems.关键词
