摘要

提出了一种用简单的线性表结构发现事务数据库中封闭频繁项集的方法——频繁模式表。该方法从候选项集中选择表示模式，减少频繁模式的组合空间。通过执行签名顶点合取和顶点计数两个操作，简化了闭项集的生成过程。

Generating Closed Frequent Itemsets with the Frequent Pattern List

An approach is proposed to discover closed frequent itemsets with a simple linear list structure called the Frequent Pattern List(FPL) in transaction database. The approach selects representation patterns from candidate itemsets to reduce combinational space of frequent patterns. By performing two operations, signature vertex conjunction and vertex counting, it simplify the process of closed itemsets generation.
