Research on Mining Maximum Frequent Itemsets Based on JFP-Growth Algorithm
The FP-Growth algorithm is the most representative frequent item set mining algorithm.An improved algorithm JFP-Growth algorithm is proposed for the shortcomings of FP-Growth algorithm.When mining the maximum frequent itemsets,the JFP-Growth algorithm traverses the support of the first 1-item set and the 2-item set of the first-time data set statistics,and uses the frequent 2-item set as the pruning condition for full pruning and The merged nodes make there is no non-potential candidate 3-item set in the JFP-tree,and the conditional pattern base is generated without traversing the project header table during the mining process.Finally,the FP-Growth algorithm and DMFIA algorithm are compared in the mining results,the number of nodes in FP-tree and JFP-tree,mining efficiency,etc.,which verifies the correctness and efficiency of the JFP-Growth algorithm proposed in this paper.
