| Abstract: | In view of the defects of traditional BP artificial neural network,the Bayesian regularization method is used for improving the generalization ability of artificial neural network.Through an engineering example,the BP artificial neural network method with Bayesian regularization is compared with L-M method and polynominal curve fitting method respectively.It is found that the improved method has better fitting precision,stability and better generalization ability,so it has good practicability in GPS height ... |
