In the machine learning tutorial, today we will learn FP Growth. This algorithm is similar to the apriori algorithm. Now see that in the Apriori algorithm, to execute each step, We have to make a candidate set. Now, to make this candidate set, our algorithm has to scan the complete da...

In subject area: Computer Science 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 extr...
