Efficient Algorithms for Mining Top-K High Utility Itemsets

July 20, 2016 by IeeeAdmin

ieee projects 2016 Tanjore(Thanjavur), Pudukkottai High utility item sets (HUIs) mining is an emerging topic in data mining, which refers to discovering all item-sets having a utility meeting a user-specified minimum utility threshold min_util. However, setting min_util appropriately is a difficult problem for users. Generally speaking, finding an appropriate minimum utility threshold by trial and error is a tedious process for users. If min_util is set too low, too many HUIs will be generated, which may cause the mining process to be very inefficient. On the other hand, if min_util is set too high, it is likely that no HUIs will be found. In this paper, we address the above issues by proposing a new framework for top-k high utility item-set mining, where k is the desired number of HUIs to be mined. Two types of efficient algorithms named TKU (mining Top-K Utility item sets) and TKO (mining Top-K utility item sets in One phase) are proposed for mining such item-sets without the need to set min_util. We provide a structural comparison of the two algorithms with discussions on their advantages and limitations. Empirical evaluations on both real and synthetic data-sets show that the performance of the proposed algorithms is close to that of the optimal case of state-of-the-art utility mining algorithms.
