如何高效而正确地挖掘关联规则是数据挖掘领域的一个重要研究方向。在现有工作的基础上结合基因表达式编程进化算法提出了一种新的挖掘强关联规则的算法框架;提出并实现了基于小生境技术的基因表达式编程算法(niche—gene expression programming,NGEP)以用于挖掘关联规则。与同类算法的对比实验结果表明,NGEP不但能更快地收敛,还进一步提高了挖掘的正确率。
Mining association rules in large databases efficiently and effectively is becoming one of the most important and popular ways of knowledge discovery. Combine with the technology of data mining and gene expression programming and niche technology, this paper put forword a new arithmetic NGEP( miche-gene expression programming). Compared with GA-AA, NGEP can gain faster convergence and better solutions.
