基于粗糙集方法的有序尺度变量选择

Ordinal Variable Selection Using Rough Set Approaches

针对一种特殊类型的变量——有序尺度变量,用基于优势关系的粗糙集属性约简方法进行变量选择.实例表明,该方法可简单有效地对有序尺度变量进行选择.

With respect to a kind of particular variables ordinal variables, variable selection is realized by using attributes reduction approaches of rough set based on dominance relation. The test shows that this approach not only successes to select variables but also gets effective conclusions.
