The Environmental Quality Evaluation of Qinhuangdao Port Regional Based on Fuzzy BP Neural Network and PSO


A fuzzy BP neural network model based on particle swarm optimization (PSO) is proposed in this paper. The basic idea of this model is, firstly, the relative membership degrees of fuzzy mathematics are used for deal with the input sample, and then use the algorithm optimizing. Secondly, PSO is used to optimize the BP neural network's initialized weights, an… (More)
