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。
Data Mining By Parallelization of Fp-Growth AlgorithmIn this paper we present idea to make one main tree on master node and slave do processing with database rather than have multiple FP-trees, one for each processor Firstly, the dataset is divided equally among all participating processors Pi....
