Mining frequent itemsets has emerged as a fundamental problem in data mining and plays an essential role in many important data mining tasks. In this paper, we propose a novel vertical data representation called N-list, which originates from an FP-tree-like coding prefix tree called PPC-tree that stores crucial information about frequent itemsets. Based on the N-list data structure, we develop an efficient mining algorithm, PrePost, for mining all frequent itemsets. Efficiency of PrePost is… CONTINUE READING
