基于规则的Apriori算法的研究与应用
首发时间:2009-09-23
摘要:本文提出了一种基于规则的Apriori算法,它是在研究传统Apriori算法的基础上从不同角度做了改进,在 Apriori算法的输入集中加入规则参数:产生候选项集规则、支持度定义规则、提取频繁项集规则,使其适用的范围更大,应用更灵活,特别是在数据项集数目比较大、项目之间的组合有限制、支持度自定义或者挖掘正负关联规则的应用中。把此算法应用在电信套餐劝转服务中,得出和用户匹配度较高的套餐。

The Research and Application of Apriori Algorithm based on rules
Abstract:This paper provides an rule-based Priori algorithm which is an improved algorithm based on the traditional Apriori algorithm. It increase one input parameter the rules which contains the rules of generating candidate set, the rules of defining support and the rules of extracting requent itemsets. It makes the algorithm more flexible, especially in the large number of data items and the data item can’t combinate freely. We applied this improved algorithm to the service of persuading the customer to change telecom package. It can tell the costomer which packages match them most.
