摘要
基于决策规则的条件属性支持度和规则支持度,结合Apriori算法思想,本文提出了一种利用决策规则支持度对粗糙集中决策表进行值约简的算法。实例表明该算法可以有效地对决策表进行值约简。
This paper presents a value reduction algorithm to reduce the decision table in Rough Sets. The algorithm is based on the support of condition attributes and the support of decision rules according to the thought of Apriori algorithm. An instance indicates that the decision table can be value-reduced effectively.
