A Proposal for System Performance Evaluation for an ERP Knowledge Extraction Model
(Proceedings of The 11th European Conference on Knowledge Management, Vols 1 and 2, 2010-01-01) [Resumo]
Much has been researched and discussed in the importance played by knowledge in organizations. We are witnessing the establishment of the knowledge economy, but this "new economy" brings in itself a whole complex system ...
Optimizing feature selection through binary charged system search
(Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), 2013-09-26) [Trabalho apresentado em evento]
Feature selection aims to find the most important information from a given set of features. As this task can be seen as an optimization problem, the combinatorial growth of the possible solutions may be inviable for a ...
A path- and label-cost propagation approach to speedup the training of the optimum-path forest classifier
(Pattern Recognition Letters, 2014-04-15) [Artigo]
In general, pattern recognition techniques require a high computational burden for learning the discriminating functions that are responsible to separate samples from distinct classes. As such, there are several studies ...
A novel algorithm for feature selection using Harmony Search and its application for non-technical losses detection
(Computers & Electrical Engineering, 2011-11-01) [Artigo]
Finding an optimal subset of features that maximizes classification accuracy is still an open problem. In this paper, we exploit the speed of the Harmony Search algorithm and the Optimum-Path Forest classifier in order to ...
What is the importance of selecting features for non-technical losses identification?
(Proceedings - IEEE International Symposium on Circuits and Systems, 2011-08-02) [Trabalho apresentado em evento]
Although non-technical losses automatic identification has been massively studied, the problem of selecting the most representative features in order to boost the identification accuracy has not attracted much attention ...
Núcleo de estudos e práticas pedagógicas: um espaço para aprender e conhecer
(Congresso Estadual Paulista sobre Formação de Educadores, 2011) [Trabalho apresentado em evento]
Difusão de tecnologia CAD e CNC como ferramenta básica de criação e produção em pequena escala, acessível à comunidade
(Proceedings of COPEC World Congress, 2011) [Artigo]
The high competitiveness and the search for newtechnologies that differentiate the product from the project,require the use of new digital tools. The computer aideddesign - Computed Aided Design (CAD), with electronicmodeling, ...
