In this paper we propose an efficient method for mining frequent intertransaction itemsets. Our approach consists in mining maximal frequent itemsets (MFI) by extending the SmartMiner algorithm for the intertransaction case. We have called the new algorithm InterTraSM (Inter Transaction Smart Miner). Because it uses depth first search the memory needed by the algorithm is reduced;a strategy for passing tail information for a node combined with a dynamic reordering heuristic lead to improved speed. Experiments comparing InterTraSM to other existing algorithms for mining frequent intertransaction itemsets have revealed a significant gain in performance. Further development ideas are also discussed.
The rapid growth of demand in mobile networks leads to peak-load traffic congestion. The congestion problem is a serious concern because it degrades the quality of service. Reducing the peak time load improves the ove...
