| 摘 要： | 新的决策表约简模型将MDP(Mean Decision Power)规则集作为最终的约简结果,解决了不相容决策表约简结果不一致的问题.在MDP规则集中,相对决策强度和规则数目是一对紧密相关的重要的参数.发现并研究了它们之间存在的关系,而这种关系的确立有助于人们深刻理解MDP规则集的本质,也为MDP规则集的增量推导算法的确立提供了重要思路.

| Abstract: | Rule set of mean decision power(MDP)is regarded as the final reduction result in the new reduction model.It contributes to solving the problem that exists in the reduction results of inconsistent decision table.In rule set of mean MDP,relative decision power(RDP) tightly associates with the number of rules(NR).This paper analyzes the relationship between RDP and NR,and presents a useful conclusion.This conclusion could help people to profoundly understand the essence of rule set of mean MDP.At the same time,the conclusion provides an important way by which we research an incremental algorithm for the new reduction model. |
