Test costs and misclassification costs are two most important types in cost-sensitive learning. In decision systems with both costs, there is a tradeoff between them while building a classifier. Generally, with more attributes selected and more information available, the test cost increases, and the misclassification cost decreases. We shall deliberately select an attribute subset such that the...

We present a theoretical analysis and empirical evaluations of a novel set of techniques for computational cost reduction of classifiers that are based on learned transform and soft-threshold. By modifying optimization procedures for dictionary and classifier training, as well as the resulting dictionary elements, our techniques allow to reduce the bit precision and to replace each floating-poi...

HIV prevalence worldwide among people who inject drugs (PWID) is around 19%. Harm reduction for PWID includes needle-syringe programs (NSPs) and opioid substitution therapy (OST) but often coupled with antiretroviral therapy (ART) for people living with HIV. Numerous studies have examined the effectiveness of each harm reduction strategy. This commentary discusses the evidence of effectiveness ...

This paper presents a PC-based thermal cycler with a local-host architecture, where a PC is employed as the host. The local system only executes the thermal cycling process and the PC is responsible for the management of PCR protocols with a convenient GUI. The presented local-host system greatly reduces the development time and the maintenance cost, providing an economical PCR thermal cycler.

A model-based approach for minimization of test sets for human-computer interactions is introduced. Test cases are efficiently generated and selected to cover the behavioral model of the system under test (SUT) and its fault model that is constructed by complementing the original model. Results known from statebased conformance testing and graph theory are used and extended to construct algorit...

Accurate simulation provides a significant means for cost reduction during planning and operation of manufacturing installations. Within the projects Realistic Robot Simulation the standards Robot Controller Simulation (RCS) Interface and Virtual Robot Controller (VRC) Interface were defined by international consortia of leading car makers, robot and simulator manufacturers and line builders, w...

Web-based Data Imputation enables the completion of incomplete data sets by retrieving absent field values from the Web. In particular, complete fields can be used as keywords in imputation queries for absent fields. However, due to the ambiguity of these keywords and the data complexity on the Web, different queries may retrieve different answers to the same absent field value. To decide the m...

at many circumstances, in heat exchange processes several exchangers were used with different cost laws due to their pressure ratings, materials of construction and exchange3r types. in such circumstances traditional methods of pinch technology can not be led to minimum total annual cost may cause some other disadvantages like more complexity or higher maintenance. in this research work a new a...

Background: The burden of obesity and diet-related chronic diseases is increasing in Iran, and prevention and treatment strategies are needed to address this problem. The aim of this study was to determine the outcome, cost, safety and cost-consequence of non-invasive weight loss interventions in Iran.   Methods: We performed a systematic review to compare non-invasive interventions (cr...
