数据挖掘中关联规则的研究

Research of Association Rule in DateMining

通过对Apriori算法的基本思想和性能的研究分析,指出Apriori算法存在一些不足。针对这些不足提出了采用比较支持计数合并频繁项集和减少扫描数据库记录个数两种方法的CRApriori算法,以提高挖掘效率。

Though analysis and study of the principle and efficiency of Apriori algorithm,point out the defect and presenting an improved algorithm by support ordering join itemsets and reducing the number of Database scanning.This paper gives an improved algorithm CRApriori,and improves the efficiency of data mining.
