《Data Mining》学习——FP-growth算法 对Apriori算法的改进 Apriori算法在挖掘事物关联规则有一定的弊端,也就是在数据量过大,而最小支持度阈值却很低的情况下,Apriori算法对事物数据库的遍历,尤其在编程过程中对组合步骤中,嵌套了过多的循环,导致挖掘效率低下。对此,做出改进的经典算法之一是FP-growth算法。 FP...
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....
