| Abstract: | The theory of ANN has been introduced. At the same time, some limitations of BP neural network have been analyzed and optimized methods have been supposed. A new method of using improved BP network is prensted to make a trainning program.The calculation shows that the performance of the improved BP network in speed of convergence and stability of convergence is very good.And the method of arificial neural network is effective in solving the Constitutive Relationship of High Polymer . |
