An Evaluation Method of Water Quality Based on Improved PSO-BP Network

Abstract:

Because of the existing problems of BP network: easily falling into local minimum point, slowly converging and generalization ability can not be guaranteed, the evaluation method of water quality based on BP network is not satisfactory. Therefore, an algorithm of improved particle swarm optimizing is used to optimize the BP network. On the basis of this, an evaluation method of water quality based on improved PSO-BP network is designed. Proved by experiments, the BP network optimized by improved PSO is stable. So, the performance and efficiency of the water quality evaluation based on improved PSO-BP is pretty good.
