Study of the Prediction Modeling of Neural Network Using the Optimal Subset

Chen Ning\ Jin Long\ Yuan Chengsong (Jiangsu Institute of Meteorology, Nanjing\ 210008)  
A method about the neural network long tem forecast is studied by using the optimal subset. The results show that the neural network model established by the optimal subset is found of better fitting and prediction accuracy, because the method using the optimal subset can select out better factors than stepwise regression. Thus it provides a new line for the research of neural network prediction on long term forecast.
