摘要: Various Artificial Neural Network techniques such as Generalized Regression Networks (GRNN), Feed Forward (FFNN) and Radial Basis (RBNN) have been evaluated based on their performance in forecasting monthly water consumptions from several socio-economic climatic factors, which affect use. The data set including total 108 records is divided into two subsets, training testing. models consisting of the combination independent variables are constructed best fit input structure investigated. ANN testing stages compared with observed consumption values to identify model. For this purpose, some criteria Normalized Root Mean Square Error (NRMSE), efficiency (E) correlation coefficient (CORR) calculated for all models. also trained tested by Multiple Linear (MLR). results indicated that GRNN outperforms other methods modeling consumptions.
