Abstract

Knowledge reduction is an important issue when dealing with huge amounts of data. Rough set theory offers two fundamental concepts to deal with this particular problem: reduct and core. These concepts are generalized to families of equivalence relations. We propose a method of implementation to calculate relative core and reducts based on the positive region of a classification with respect to another classification. We use families of equivalence relations instead of classifications.
一种计算相对核和约简的有效实现
在处理大量数据时,知识约简是一个重要的问题。粗糙集理论提供了两个基本概念来处理这个特殊的问题:约简和核心。这些概念被推广到等价关系族。我们提出了一种基于一个分类相对于另一个分类的正区域来计算相对核心和约简的实现方法。我们使用等价关系族代替分类。
