Using large regressors in non-linear time series forecasting makes the fitting of the model difficult. This paper shows how to reduce the size of regressors in order to improve the forecasting performances, using the Curvilinear Component Analysis as projection tool. The method is applied to the Polish electrical load forecasting.
