摘要: 在分析FP_growth 关联规则挖掘算法的基础上,提出了一种MFP 的算法,给出了算法的工作原理。 MFP 算法能在一次扫描事务数据库过程中,把该数据库转换成MFP 树,然后对MFP 树进行关联规则挖掘。MFP 算法比FP_growth 算法减少一次对事务数据的扫描,因此具有较高的时间效率。

Abstract: Based on fully analyzing the FP_growth, an association rule mining algorithm, this paper presents a new association rule mining algorithm called MFP. The MFP algorithm can convert a transaction database into a MFP tree through scanning the database only once, and then do the mining of the tree. Because the MFP algorithm scans a transaction database one time less than the FP_growth algorithm, the MFP algorithm is more efficient with time.
