Mining Frequent Closed Itemsets with One Database Scanning
Yong Qiu, Yong-Jie Lan · 2006
Frequent closed itemsets mining has become an important alternative of association rule mining recently. CloSET+ is an efficient algorithm to find frequent closed itemsets without candidate generation. However, CloSET+ must scan database two times. In order to enhance the efficiency of CloSET+ algorithms and reduce the I/O cost of database scanning in frequent closed itemsets mining, propose a novel algorithm called QCloSET+ which can mining frequent closed itemsets with one database scanning
