FP-Growth-算法 该存储库包含用于(市场篮子)数据集中规则挖掘的 FP-Growth-Algorithm 的 C/C++ 实现。 描述 主文件 - 这是驱动程序。 它从用户输入数据集、最小支持度 (0-100) 和最小置信度 (0-1) FP_TREE_GEN.c - 该程序通过输入数据集,首先找到每个项目的支持,从数据集中删除所有不常见的项目,根据...
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...
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....
Based on analyzing an association rule mining algorithm called FP tree. a new association rule mining algorithm called Enhanced FP was presented. As the main disadvantage of FP-Growth is that it is very difficult to implement because of its complex data structure. In this FP-tree takes a lot...
FP-Tree(不产生频繁候选集) FP-Tree增长算法的步骤：(1)建立FP-tree树 扫描数据库一次，找出频繁1-项集，按递减顺序排序。再一次扫描数据库，建立FP-tree。 (2)利用FP-tree挖掘频繁集 对于每一个项，先构造条件模式基，然后构造条件FP-树。在每一个新创建的条件FP-树上重复此过程。
