Attribute Reduction of Interval-Valued Information System Based on Fuzzy Discernibility Matrix
摘要
Abstract
We proposes a new method to measure the similarity of two interval values,this measurement is based on physical measuring and error processing theory,so it is more reasonable than original methods. Moreover,we introduce a new method of attributes reduction with fuzzy discernibility matrix. We also discuss a discretization argument of the similarity measurement function, which helps to improve the system robustness.关键词
