| Abstract: | To solve the problem of getting into local optimal solution that neural network algorithm faces when used in GPS height conversion,a combination model of genetic algorithm and neural network is proposed and the framework and algorithm of this model is also discussed.Experimental results demonstrated that this combination model can not only solve the problem of getting into local optimal solution,but also can increase the convergence rate,computing accuracy and efficiency of neural network. |
