dc.description.abstractThe objective of the high-utility itemset mining task is to figure out the item or the combination of items which achieve the high profits from the database. The proposed algorithm named HUIM is considered as a advantageous tool to analyze the customer behavior. Nevertheless, the item categories are not considered. The ML-HUI Miner algorithm was suggested in order to solve this problem. It not only uses the HUIM task but also combine with the taxonomy to get the group of high utility itemsets in many levels. Though the ML-HUI Miner is successful in discovering itemsets from many abstractions level, it may not optimize for some databases. As a result, it cannot present all the wonderful of the algorithm. This paper goes through these issues by extending the previous algorithm with adding transaction merging process version to help decrease not only the running time but also the memory usage. The list of items per level on transaction in the database will be merged into ones for eliminating the mining time in similar transaction. The experiment on the real dataset and synthesis dataset show that the improvement of algorithms is faster than the original algorithmen_US
