Abstract: Abstract:In this paper, we use maximal itemsets to represent itemsets in a database. We show that the set of supreme covers, which are the maximal itemsets whose proper subsets are not maximal itemsets, induces an equivalence relation on the set itemsets. Based on maximal itemsets, we propose a large itemset generation algorithm with dynamic support, which runs in time O(M′2N+M′logM), where N is the maximum number of items in a maximal itemset, M′ is the number of the maximal itemsets with minimum support greater than the required support, and M is the number of the maximal itemsets.
