CONVERSION OF GPS HEIGHT BASED ON STANDARDIZATION MOMENTUM BP NEURAL NETWORK
基于标准化动量BP神经网络的GPS高程转换

When solving fitting elevation by using common momentum BP neural network algorithm there will be difference between the training samples in dimension.In order to improve the stability we standardized the samples and obtained the ideal results.It is shown that from the comparison among the results with the calculation methods by surface fitting,quadric surface fitting,and other neural network methods,the accuracy by using the standardization of BP neural network algorithm for elevation fitting is more relia...
