Quanxi Xia · Shipbuilding of China · 2009
The LM algorithm is the combination of the steepest decent algorithm with the Gauss-Newton algorithm.Concerned with the training process and accuracy,the LM algorithm is superior to traditional BP algorithm introduced in this paper.An improved algorithm of traditional BP based on LM(Levenberg-Marquardt) algorithm is proposed and applied to the fault diagnosis of marine integrated navigation system.Simulation results illustrate that LM algorithm could speed up learning process and reduce training time effectively.The diagnostic effect is good.
