Many solutions to cost-sensitive classification (and regression) rely on some or all of the following assumptions: we have complete knowledge about the cost context at training time, we can easily re-train whenever the cost context changes, and we have technique-specific methods (such as cost-sensitive decision trees) that can take advantage of that information. In this paper we address the pro...

Each of n processors has a value which should be transmitted to all other processors. This fundamental communication task is called gossiping. In a unit of time every processor can communicate with at most one other processor and during such a transmission each member of a communicating pair learns all values currently known to the other. Two important criteria of eeciency of a gossiping algori...

Jakob Axelsson,

This paper presents a model for estimating the total cost of a proposed electronic architecture for embedded, distributed, real-time systems. The main purpose of the model is to allow system engineers to compare different solution alternatives with respect to cost, in order to perform an early optimization. This is necessary to cope with the complexity of such systems, and make them profitable ...

The early models of Islamic banks are based on partnership of mudharaba and musharaka (profit-loss sharing) structure. Such equitybased financing are perceived to be superior to conventional financing from the standpoint of robustness to external shocks and from the standpoint of ethics, fairness and social justice. Where profit-loss sharing mechanisms cannot be used, Islamic banks provide othe...

Algorithms for crowdsourced tasks such as entity resolution, sorting, etc. have been subject to a variety of research work. So far, all of this work has focused on one specific problem respectively. In this paper, we want to focus on the bigger picture. More specifically, we want to show how it is possible to estimate the budget or the quality of an algorithm in a crowdsourcing environment wher...

This paper presents a multi-objective resource-constrained project scheduling problem with positive and negative cash flows. The net present value (NPV) maximization and making span minimization are this study objectives. And since this problem is considered as complex optimization in NP-Hard context, we present a mathematical model for the given problem and solve three evolutionary algorithms;...

Time-cost trade-off is one of the most important subjects in project management and of interest to contractors. The goal of time-cost trade-off is sensivity analysis of project costs to changes in activity duration in order to obtain the best combination of activity duration decrease, in a way that the sum of project costs is minimized. In the heuristics presented in this area, time crashing is...

In this paper, an efficient multi-objective model is proposed to solve time-cost trade off problem considering cash flows. The proposed multi-objective meta-heuristic is based on Ant colony optimization and is called Non Dominated Archiving Ant Colony Optimization (NAACO). The significant feature of this work is consideration of uncertainties in time, cost and more importantly interest rate. A ...
