基于粗糙集理论的不完备决策表的完备化方法

A Completion Algorithm of Incomplete Decision Table

首先针对不同的条件属性类型,分别给出两对象关于条件属性的相似度,然后给出了t相似度的概念,最后分别就条件属性是离散、连续、序数型的决策表给出了相应的完备化(补齐)算法.实例表明此完备化方法是行之有效的.

First, we give the similarity degree definition of two objects according to different kinds of condition attributions respectively. Then we get the definition of t similarity degree. At last, the completion algorithm is given. Examples show that the algorithm is valid.
