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....
Additionally, the header table of the NFP-tree is smaller than that of the FP-tree. Therefore, the total number of nodes of all conditional trees can be reduced. Simulation results reveal that the NFP-growth algorithm is superior to the FP-growth algorithm for dense datasets and real ...

提出了一种利用FP树表示增量数据库,然后进行增量挖掘的方法,即IA_FP-Growth算法.算法重构和合并两个小的时间上连续的FP树,以获得由FP-Growth算法生成的FP树.与其他从数据库读取事务的顺序增量算法不同,IA_FP-Growth算法使用原FP-tree作为预处理数据库来获取项目集,因此其花费较少的时间来构建新的增量FP-tree项目...

在实践中,FP Tree算法是可以用于生产环境的关联算法,而Apriori算法则做为先驱,起着关联算法指明灯的作用。除了FP Tree,像GSP,CBA之类的算法都是Apriori派系的。 经典案例和代码实现: 以下是一个使用Python的mlxtend库实现FP-Growth算法的示例代码: from mlxtend.frequent_patterns import fpgrowth ...
