一种序决策表的特征选择算法

A Feature Selection Algorithm of Ordered Decision Tables

本文基于序意义下优势类的概念,提出了序决策表的一种条件依赖度,从而给出了序决策表中属性重要度的定义。在此基础上,设计了一种序决策表的特征选择算法,并通过实例分析对算法进行了有效性检验。

In this paper,a kind of new condition dependability is proposed for ordered decision tables based on dominance classes,which can be used to give the definition of attribute significance. Then,a feature selection algorithm is put forward for ordered decision tables,and the validity of this algorithm is exemplified by an illustrative example.
