where each node has one or more node attributes. Specifically, we extend CT index, allowing it to handle node attributes by using BAG index within a short index construction time (Sect.4.1).
Computer Science, Peking University, Beijing 100871, China article info Keywords: Data mining Frequent itemset mining Nodesets Algorithm Performance abstract Node-list and N-list, two novel data structure proposed in recent years, have been proven to be very efficient for mining frequent itemsets. ...
We also present a new algorithm, using diffsets, for mining maximal patterns. Experimental comparisons, on both dense and sparse databases, show that diffsets deliver order of magnitude performance improve- ments over the best previous methods. 1 Introduction Mining frequent patterns or itemsets is ...
