Economic Growth Prediction Using Optimized Support Vector Machines

Abstract

The main objective of this research is to propose a new hybrid model called genetic algorithms-support vector regression (GA-SVR). The proposed model consists of three stages. In the first stage, after lag selection, the most efficient features are selected using stepwise regression algorithm (SRA). Afterward, these variables are used in order to develop proposed model, in which the model uses support vector machines that the parameters of which are tuned by GA. Finally, evaluation of the proposed model is carried out by applying it on the test data set.
