The storage structure for sequence in existing incremental mining algorithms of sequential patterns is used to store the sequences that meet the support threshold. When the database is updated, the projected database needs to be constructed to find the sequential patterns in the updated database. In this paper, we propose the structure of sequence tree based on projected database, called sequence...
As one of the most important problems in data streams mining, many studies have been done on mining closed frequent itemsets. However mining closed frequent itemsets in data streams has not been well addressed. In this paper, we design HCI-Mtree (Hash-based Closed Itemsets Monolayer tree) to maintain the complete set of current closed itemsets. In HCI-Mtree, the itemsets with the same frequency are...
