In this paper we address the problem of budget allocation for redundantly crowdsourcing a set of classification tasks where a key challenge is to find a trade–off between the total cost and the accuracy of estimation. We propose CrowdBudget, an agent–based budget allocation algorithm, that efficiently divides a given budget among different tasks in order to achieve low estimation error. In part...

In this paper we investigate the interplay between operational and financial decisions within the context of a two-echelon supply chain. A retailer purchases a single product from a supplier and afterwards sells it in the retail market to a random demand. The retailer, however, is budgetconstrained and is therefore limited in the number of units that he may purchase from the supplier. We study ...

This chapter describes the integrated security verification and security solution design trade-off analysis (SVDT) approach. SVDT is useful when there is a diverse set of requirements imposed upon a security critical system, such as a required security level, time-to-market and budget constraints and end users’ expectations. Balancing these needs requires developers to evaluate alternative secu...

Digital crowdsourcing (CS) is a modern approach to perform certain large projects using small contributions of a large crowd. In CS, a taskmaster typically breaks down the project into small batches of tasks and assigns them to so-called workers with imperfect skill levels. The crowdsourcer then collects and analyzes the results for inference and serving the purpose of the project. In this work...

this descriptive cross sectional census study identified the perceptions of extension and outreach employees of iowa state university in the united states about job autonomy and control after two years of a major restructuring. employees perceived autonomy and control over expressing views and ideas about their work and spending time on the job but perceived little influence over budget allocat...

We consider the problem of representation of a finite-energy optical field, with a finite number of bits. The optical field is represented with a finite number of uniformly spaced finite-accuracy samples (there is a finite number of amplitude levels that can be reliably distinguished for each sample). The total number of bits required to encode all samples constitutes the cost of the representa...

Ab t t www. Adaptive schemes, where tasks are assigned based on the data collected thus far, are widely used in practical crowdsourcing systems to efficiently allocate the budget. However, existing theoretical analyses of crowdsourcing systems suggest that the gain of adaptive task assignments is minimal. To bridge this gap, we propose a new model for representing practical crowdsourcing system...

The final goal, for the foreseeable future, of the Human Exploration of the Solar System is to land a crew on the Mars Surface (and to bring it back). A wide array of capabilities has to be developed and demonstrated before attempting such a risky endeavor; intermediate steps are therefore needed, also to comply with budget constraints. Human missions to Near Earth Objects (NEOs) and specifical...

We consider the problem of estimating the arithmetic average of a finite collection of real vectors stored in a distributed fashion across several compute nodes subject to a communication budget constraint. Our analysis does not rely on any statistical assumptions about the source of the vectors. This problem arises as a subproblem in many applications, including reduceall operations within alg...
