Title in English
Neural networks as an optimization method for regression
Keywords in English
Ensembles
Local regression
Neural networks
Optimization
Regression
Abstract in English
Neural networks are a tool to solve prediction problems that have gained much prominence recently. In general, neural networks are used as a predictive method, that is, their are used to estimate a regression function. Instead, this work presents the use of neural networks as an optimization tool to combine existing regression estimators in order to obtain more accurate predictions and to fit local linear models more efficiently. Several tests were conducted to show the greater efficiency of these methods when compared to the usual ones.

Abstract in Portuguese
Redes neurais são uma ferramenta para resolver problemas de predição que ganharam muito destaque recentemente. Em geral, redes neurais são utilizados como um método preditivo, ou seja, estimando uma função de regressão. Este trabalho, no entanto, apresenta o uso de redes neurais como uma ferramenta de otimização para combinar estimadores de regressão já existentes de modo a obter predições mais precisas e ajustar modelos lineares locais de forma mais eficiente. Vários testes foram conduzidos para mostrar a maior eficiência desses métodos quando comparados aos usuais.
