On-shelf utility mining with an upper-bound measure

This paper handles the problem of finding high on-shelf utility itemsets, which considers not only individual profit and quantity of each item in a transaction but also on-shelf periods of the items. We have extended our previous approach by designing an efficient pruning strategy based on an on-shelf utility upper-bound measure to early prune the unpromising candidates in the mining process. Experimental results also show its performance. ICIC International
