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...

FP-growth algorithm is an algorithm for mining association rules without generating candidate sets. It has high practical value in many fields. However, it is a memory resident algorithm, and can...doi:10.1007/978-981-10-6385-5_15Kuikui Jia...
This module provides a pure Python implementation of the FP-growth algorithm for finding frequent itemsets. FP-growth exploits an (often-valid) assumption that many transactions will have items in common to build a prefix tree. If the assumption holds true, this tree produces a compact representat...
The FP-Growth algorithm, based on FP-Tree, needs to create a large number of conditional FP-Trees recursively in the process of mining frequent patterns. It is not efficient and not good to apply in mobile communication business cross-selling, in which the association rules mining is business...
