Research on algorithms for association rules mining based on FP-tree

Technology of frequent pattern tree is presented in the paper. This paper analyzes the defect and limitation of algorithm based on classic frequent pattern of association rules. Then based on KDD* model this article implement an association rules algorithms based on IFP-tree. The middle results and finally frequent patterns of the algorithm are stored on database. The algorithm in build IFP-tree and speed of mining frequent patterns has certain improvement. Finally, the experiments reports in the paper confirmed that IFP-tree algorithm if effective and reliable for mining association rules.
