The FP-growth algorithm is defined as a distributed implementation that utilizes the MapReduce paradigm to extract the most frequent closed itemsets from a dataset. It involves building independent FP-trees and running a local main memory FP-growth algorithm to extract frequent itemsets associated with...

在Apriori算法原理总结中,我们对Apriori算法的原理做了总结。作为一个挖掘频繁项集的算法,Apriori算法需要多次扫描数据,I/O是很大的瓶颈。为了解决这个问题,FP Tree算法(也称FP Growth算法)采用了一些技巧,无论多少数据,只需要扫描两次数据集,因此提高了算法运行的效率。下面我们就对FP Tree算法做一个总结。
An example is used to analyze the relationship between different items in the transaction database,and then the voter’s vote is analyzed, so as to konw the voter’s party perference. Key words:Data Mining;Association rules;FP-growth algorithm 1 1.1 世界日新月异,信息瞬息万变,数据是信息的...
use another algorithm, for example FP Growth, which is more scalable. Seethis blogfor some details on Apriori vs. FP Growth. Or do both of the above points by using FPGrowth in Spark MLlib on a cluster. And the nice thing is: you can stay in your familiar R Studio environment!
