Finding Fast Changing Patterns In the presence of hierarchy
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 1
Abstract
History Generalized Algorithm is used in this paper which is used to find the generalized as well as non generalized itemsets .after finding those itemsets find out the particular node in the tree structure and attach those itemsets in specific order. One dynamic pattern, the history generalized pattern ,that represents the development of an itemset in successive time periods, by accounting the information about its recurrent generalizations characterized by minimal redundancy some time it becomes infrequent. Higen mining, The higen miner, that focuses on avoiding itemset mining followed by postprocessing by developing a supportdriven itemset generalization .To focus the attention on the minimally redundant recurrent generalizations and reduce the amount of the generated patterns, the finding a subset of higens, namely the nonredundant higens, . Tests do on both real and synthetic datasets show the competence and the effectiveness.
