Cost-effective clustering [PDF]
Small Beowulf clusters can effectively serve as personal or group supercomputers. In such an environment, a cluster can be optimally designed for a specific problem (or a small set of codes). We discuss how theoretical analysis of the code and benchmarking on similar hardware lead to optimal systems.

Bayesian models for cost-effectiveness analysis in the presence of structural zero costs [PDF]
Bayesian modelling for cost-effectiveness data has received much attention in both the health economics and the statistical literature in recent years. Cost-effectiveness data are characterised by a relatively complex structure of relationships linking the suitable measure of clinical benefit (\eg QALYs) and the associated costs.

First-Order Dynamic Optimization for Streaming Convex Costs [PDF]
This paper proposes a set of novel optimization algorithms for solving a class of convex optimization problems with time-varying streaming cost function. We develop an approach to track the optimal solution with a bounded error. Unlike the existing results, our algorithm is executed only by using the first-order derivatives of the cost function which ...

Cost-sensitive C4.5 with post-pruning and competition [PDF]
Decision tree is an effective classification approach in data mining and machine learning. In applications, test costs and misclassification costs should be considered while inducing decision trees. Recently, some cost-sensitive learning algorithms based on ID3 such as CS-ID3, IDX, \lambda-ID3 have been proposed to deal with the issue. These algorithms

Do Users Care about Ad's Performance Costs? Exploring the Effects of the Performance Costs of In-App Ads on User Experience [PDF]
Context: In-app advertising is the primary source of revenue for many mobile apps. The cost of advertising (ad cost) is non-negligible for app developers to ensure a good user experience and continuous profits. Previous studies mainly focus on addressing the hidden performance costs generated by ads, including consumption of memory, CPU, data traffic ...

Optimal Selection of Transaction Costs in a Dynamic Principal-Agent Problem [PDF]
Environments with fixed adjustment costs such as transaction costs or \lq menu costs\rq$ $ are widespread within economic systems. The presence of fixed minimal adjustment costs produces adjustment stickiness so that agents must choose a sequence of points at which time to perform their actions.

Very cost effective bipartition in Gamma(Z_n) [PDF]
Let Z_n be the finite commutative ring of residue classes modulo n and Gamma(Z_n) be its zero-divisor graph. The nilradical graph and non-nilradical graph of Z_n are denoted by N(Z_n) and Omega(Z_n) respectively. In 2012, Haynes et al. [5] introduced the concept of very cost effective graph.

Cost-Sensitive Label Embedding for Multi-Label Classification [PDF]
Label embedding (LE) is an important family of multi-label classification algorithms that digest the label information jointly for better performance. Different real-world applications evaluate performance by different cost functions of interest. Current LE algorithms often aim to optimize one specific cost function, but they can suffer from bad ...

Indirect Costs and Cost-Effectiveness Analysis
This article examines the methodological implications of the societal perspective in cost-effectiveness analyses in which the costs of health-care interventions are defined as the sums of direct and indirect costs. In the model of cost-effectiveness analysis in which the planner distributes patients among many treatments for many illnesses, the ...

Effectiveness Is the Key to Cost-Effectiveness [PDF]
Health care spending has risen faster than the rest of the United States economy for the past several decades, and is now swamping federal and state government budgets. The rising cost of health care has important consequences: either spending on other programs (eg, education, public safety, and infrastructure) must be reduced, or taxes must rise, or ...
