FIM mining spark parallelization (aPriori,p_growth)

Frequent itemset mining algorithm of mining parallel using spark (aPriori algorithm for parallel and parallel algorithm for   fp_growth b). APriori algorithm written by Scala in parallel, parallel fpgrowth written with Java. There may have more functions to make programming content.  ...

C4.5--using the JAVA realization algorithm of decision tree

C4.5 is a series of classification problems in machine learning and data mining algorithms. Its goal is to monitor: given a set of data, where each tuple is a set of attribute values are used to describe each tuple is a mutually exclusive category of some kind. C4.5 's goal was to learn, find a mapp...
