摘要

Association rule mining is one of the important data mining techniques. It finds correlationsamong attributes in huge dataset. Those correlations are used to improve the strategy of the futurebusiness. The core process of association rule mining is to find the frequent patterns (itemsets) in hugedataset. Countless algorithms are available in the literature to find the frequent itemsets. Most of thealgorithms introduced in the literature finds all frequent itemsets for a given specified minimum supportvalue. But in rare occasion, it is needed to check the occurrence of some predefined few frequent patternsin large dataset to improve the strategy of the future business. For this purpose, we previously introducedSIFPMM (Selective Itemsets Frequent Pattern Mining Method) method. FP-tree is one of the importantmethods for finding frequent patterns using two database scans. So this proposed TM-PIFPMM(Transaction Merging – Predefined Itemsets Frequent Pattern Mining Method) finds frequent patternsfrom predefined frequent itemsets using one database scan and it is compared with FP-tree andSIFPMM. The practical study of TM-PIFPMM proves that this method outperforms than FP-tree andSIFPMM.
