【摘要】 关联规则是数据挖掘中研究的一个重要课题,在对关联规则算法模型中的Apriori算法分析后,提出了基于哈希表的算法;阐述了利用哈希技术可以有效地生成最大项目集,尤其是最大二维项目集的算法过程。通过使用该技术,生成的最大项目集数量大大减少,从而提高整个过程中的执行效率。更多还原

【Abstract】 The association rule is an important topic in the research of data mining.This article puts forward the arithmetic based on the hash table after analyzing the Apriori arithmetic in the arithmetical model of the association rule,which interprets that the arithmetical produces maximal item-sets,especially the maximal two-dimension ones are produced effectively by the hash technology. By using this technology,the perform efficiency is increased greatly during the whole process and the maximal item-sets are decreased enormously.更多还原
