Bay Vo, Tuong Le, Tzung-Pei Hong, Bac Le; Maintenance of a Frequent-Itemset Lattice Based on Pre-large Concept; Knowledge and Systems Engineering, Advances in Intelligent Systems and Computing, Vol. 245 (2014), pp. 295-305 (Book Chap.).


This paper proposes an effective approach for the maintenance of a frequent-itemset lattice in incremental mining based on the pre-large concept. First, the building process of a frequent-itemset lattice is improved using a proposed theorem regarding the paternity relation between two nodes in the lattice. Then, based on the pre-large concept, an approach for maintaining a frequent-itemset lattice with dynamically inserted data is proposed. The experimental results show that the proposed approach outperforms the batch approach for building the lattice in terms of execution time.
