Numerous studies have shown that ANN (Artificial Neural Networks) performs better than traditional regression model on air quality predicting. For better performance, an improved ANN model, called GA-ANN, is proposed, in which GA (genetic algorithm) is used to select a subset of factors from the original set and the GA-selected factors are fed into ANN for modeling and testing. In the experiments,...
