Research on Air Quality Assessment Method of Civil Air Defense Engineering Based on Improved Extension Neural Network

Using the extension neural network to construct air quality evaluation model for civil air defense engineering,when we take more air pollution factors into account,the computation of training the extension neural network is larger and the convergence is more difficult.In view of this situation,the grey relational clustering theory is introduced,considering the intrinsic relationship between air pollutants,an air quality evaluation method based on grey correlation clustering performance optimization is proposed.Firstly,grey correlation clustering method is used to calculate the correlation degree between air pollutants and cluster analysis.Then,we can use the extension neural network air quality evaluation model to evaluate the air quality of civil air defense engineering based on the results of the air pollution cluster.Finally,by verifying and analyzing the optimized model,we can find that when we use the theory of the gray correlation clustering to cluster the air pollutants and then use the extension neural network to evaluate the air quality of civil air defense engineering,which can ensure that the calculation results are not distorted while improving the computational efficiency of the extension neural network.This method provides a new idea for the air quality assessment of civil air defense engineering.
