Mining of High Average-Utility Itemsets with a Tighter Upper-Bound Model

  • Abstract

    In this paper, we presented a tighter upper-bound model to instead of the traditional auub model for mining the HAUIs. A modified average-utility-list structure is also designed to keep the necessary information for later mining process, thus reducing the multiple database scans. Two pruning strategies are also respectively developed to reduce the search space for exploring the HAUIs compared with the state-of-the-art approach. Experiments showed that the designed algorithm with the new upper-bound model outperforms the traditional approach in terms of runtime and number of join operation.
