High utility itemset mining (HUIM) is a new emerging field in data mining which has gained growing interest due to its various applications. The goal of this problem is to discover all itemsets whose utility exceeds minimum threshold. The basic HUIM problem does not consider length of itemsets in its utility measurement and utility values tend to become higher for itemsets containing more items...

the rate of time preference plays an important role in discounting instantaneous utility in economic growth models and also in calculating social discount rate in cost-benefit analysis. in empirical researchers, this rate is assumed to be constant. however, the rate of time preference might vary over time. this paper develops a new algorithm to estimate this rate as a varied coefficient for the...

In this paper, we consider the use of an application-layer performance measure — the utility — in the context of bandwidth allocation for an available bit rate service. Our bandwidth allocation scheme can be viewed as a generalization of traditional available bit rate service; our scheme is equivalent to bandwidth max-min allocation when the utility of all applications are equal. The goal of ou...
