Nowadays, the BP network algorithm has achieved a great success and many nonlinear problems can be solved well. However, standard BP network algorithm has some Shortcomings. Such as local minimum, low convergence and oscillation effects etc. GA has a strong macro-search capability. It has some advantages. Such as simple and universal, robust, parallel computing features, so use it to complete the...
Combining the gray histogram of images, using the maximal cross-entropy function as the fitness function of Adaptive Genetic Algorithm, adopting Adaptive Genetic Algorithm to search the optimal threshold function, a multi-target image segmentation algorithm is put forward based on the improved PCNN model.It can effectively complete image segmentation, and the results are superior to the Ostu multi-threshold...
With the fast development of mobile ad hoc networks (MANETs), fault diagnosis has become a critical need to guarantee robust service for various applications. Many techniques have been suggested to solve this problem, but they still cannot satisfy the special need of MANETs. In this paper, we propose a new fault diagnosis system using hybrid GA-BP neural network. The results of simulation demonstrate...
