Uma Introdução às Support Vector Machines
(Instituto de Informática - Universidade Federal do Rio Grande do Sul, 2007)
Time–Adaptive Support Vector Machines
(Asociación Española de Inteligencia Artificial, 2011)
Abrupt change detection with One-Class Time-Adaptive Support Vector Machines
We recently introduced an algorithm for training a sequence of coupled Support Vector Machines which shows promising results in the field of non-stationary classification problems Grinblat, Uzal, Ceccatto, and Granitto ...
An effective power quality classifier using wavelet transform and support vector machines
(Pergamon-Elsevier Science Ltd, 2015-09)
In this paper we propose a method based on a combination of binary classifiers which are optimized for those special cases where the real signals contain a multitude of events within the analyzed temporal window. These ...
Simultaneous preference estimation and heterogeneity control for choice-based conjoint via support vector machines
(Palgrave Macmillan Ltd., 2017)
Support vector machines (SVMs) have been successfully used to identify individuals' preferences in conjoint analysis. One of the challenges of using SVMs in this context is to properly control for preference heterogeneity ...
Measuring time series predictability using support vector regression
(TAYLOR & FRANCIS INC, 2008)
Most studies involving statistical time series analysis rely on assumptions of linearity, which by its simplicity facilitates parameter interpretation and estimation. However, the linearity assumption may be too restrictive ...
Nonstationary regression with support vector machines
In this work, we introduce a method for data analysis in nonstationary environments: time-adaptive support vector regression (TA-SVR). The proposed approach extends a previous development that was limited to classification ...
Estimativa da radiação solar ultravioleta em Botucatu/SP/Brasil utilizando máquina de vetores de suporte (SVM)
In this papper is evaluated the estimation of daily solar ultraviolet radiation (UV) using Support Vector Machine (SVM) in Botucatu/SP/Brazil. We tested five groups of input data containing different weather variables. A ...
