摘要
首次提出了利用幂集作为挖掘关联规则的工具,给出了基于幂集的关联规则挖掘算法。该算法有效解决了传统算法中需对数据库多次扫描的不足,实现了对数据库一次扫描就可挖掘出所有频繁集的功能。
This paper firstly presents a power set-based association rules mining algorithm which uses pow er set as an association rules mining tool.This algorithm effectively solves th e problem that traditional algorithm needs to access database many time s in ord er to mining all the frequent itemsets and implement s the function that all th e frequent itemsets can be minded by scanning the database for only one time.
