Prediction of PM_(10) Pollution Concentration in Heating Season Based on Genetic Algorithms and Neural Network

LIU Yan-hua et al(Environment and Municipal Engineering Institute,Xian University of Architecture and Technology,Xian,Shaanxi 710055)  
The GA algorithm combining with BP algorithm was used to forecast PM10 pollution concentration of Xian.Firstly,GA algorithm optimized BP neural network models of initial weight,using BP algorithm train the network accurately,forecasting the concentration.The example showed that GA-BP neural network solved the problems of BP neural network slow convergence speed and apted plunging infinitesimal data and increased the forecasting accuracy.
