主 题:Data mining Association rules Support function Frequent pattern tree
摘 要:In this letter, on the basis of Frequent Pattern(FP) tree, the support function to update FP-tree is introduced, then an Incremental FP (IFP) algorithm for mining association rules is proposed. IFP algorithm considers not only adding new data into the database but also reducing old data from the database. Furthermore, it can predigest five cases to three *** algorithm proposed in this letter can avoid generating lots of candidate items, and it is high efficient.
