| Abstract: | Since BP algorithm had the defects that the speed of constriction was slow and had local extreme data,the modified BP algorithm was put forward.Using the collected real time data,the results indicated that the modified BP algorithm could improve the training speed and stability of Elman network effectively so that Elman neural network could realize short-time prediction for vertical displacement of wave compensating platform more effectively. |
