摘要
频繁项集挖掘是许多数据挖掘任务中的关键问题,也是关联规则挖掘算法的核心,所以提高频繁项集的生成效率一直是近几年数据挖掘领域研究的热点之一。本文以频繁项集挖掘算法的搜索方式和计数方式为主线,分析频繁项集挖掘中的代表性算法及其中的关键技术和方法,对近年来相关研究的新进展做了介绍和评述,并指出了未来的研究方向。
Mining the frequent itemset is a key problem of data mining, it is also the core of the algorithm for mining association rules. Therefore,to improve the efficiency of discovering the frequent itemsets is the issue in data mining area. In this paper, making the search methods and counting ways of the frequent intemsets mining algorithms as the main line, analyses the key technologies and methods of the representative frequent itemsets mining algorithms, and introduces the new developments of the research in this area, and disscusses the future direction of the research.
