| Abstract: | In the paper,an interpolation method is used according the standard to generate enough samples,and improved LM algorithm used to train the model to accelerate convergence and raise generalization ability.The model can comprehensively evaluate the water qualities of source sections in East Route of South-to-North Water Diversion Project through 8 years of continuous water quality monitoring data.A Hopfield neural network models of the data is also established to make an objective,comprehensive water environment quality,and suggestions for improvement are given according to the specific standard index gives. |
