| Abstract: | the traditional BP algorithm mainly exist in the network convergence speed,easy to fall into local minimum problem.According to the classic BP algorithm problems,this paper puts forward a new incentive function,and combined use of some advanced techniques on artificial neural network is improved,the improved algorithm has faster convergence speed,and can effectively avoid the algorithm being trapped in local minima. |
