(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCC, 2012-11-19)
This work proposes two new techniques of feature vector pre-processing to improve CBIR and image classification systems: a method of feature transformation based on the k-means clustering approach (Feature Transformation ...
Análise comparativa de custos: custo padrão x custo real x custo ideal
(Universidade Tecnológica Federal do ParanáPato Branco, 2014-04-21)
This study arose in order to demonstrate the importance of the approximations of the findings and analyzes of costs that occur in the production processes of enterprises, which may affect, significantly, the financial ...
Feature Selection using Associative Memory Paradigm and Parallel Computing
(Computación y Sistemas; Vol. 17 No. 1, 2013-03-06)
Abstract: Performance of most pattern classifiers is improved when redundant or irrelevant features are removed. Nevertheless, this is mainly achieved by highly demanding computational methods or successive classifiers’ ...
Simultaneous feature selection and heterogeneity control for SVM classification: an application to mental workload assessment
(Elsevier, 2020)
In this study, an expert system is presented for analyzing the mental workload of interacting with a mobile phone while facing common daily tasks. Psychophysiological signals were collected from various devices, each ...
Convolution based feature extraction for edge computing access authentication
(IEEE Computer Soc, 2020)
In this article, a convolutional neural network (CNN)
enhanced radio frequency fingerprinting (RFF) authentication
scheme is presented for Internet of things (IoT). RFF is a
non-cryptographic authentication technology, ...
Accounting for cost heterogeneity on the demand in the context of a technician dispatching problem
(Elsevier, 2020)
In the technician dispatching problem, a given number of repair teams must visit different locations to provide service support. Considering that there is a fixed vehicle capacity and variations in the demand, not all ...
Inferences from stated preference surveys when some respondents do not compare costs and benefits
Stated preference surveys are often used to estimate willingness to pay
(WTP) for environmental improvements. These surveys typically ask
respondents to choose between the status quo and one or more environmental ...
