Robust short term prediction using combination of linear regression and modified probabilistic neural network model

Abstract

In many business applications, accurate short term prediction is vital for survival. Many different techniques have been applied to model business data in order to produce accurate prediction. Artificial neural network (ANN) have shown excellent potential however it requires better extrapolation capacity in order to provide reliable prediction. In this paper, a combination of piecewise linear regression model in parallel with general regression neural network is introduced for short term financial prediction. The experiment shows that the propwed hybrid model achieves superior prediction performance compared lo the conventional prediction techniqufs such as the MultiLayer Perceptron (MLP) or Volterra series based prediction.
