[0078] (Example 1)
[0079] see Figure 3 to Figure 6 , The present invention is a method for predicting air quality based on a neural network index of a decision tree, which includes the following steps:
[0080] (1) Establish a time series data set of relevant meteorological factors, air quality and air pollutant emissions;
[0081] (2) Use the decision tree DT algorithm to classify the acquired training samples to generate the optimal tree structure T oriented by air quality characteristics α And its corresponding classification results;
[0082] (3) According to the classification results, establish a BP neural network model for each classification and conduct model training;
[0083] (4) Input the prediction data set, classify and index based on the decision tree, select the trained DT-BP neural network model or the integrated BP neural network to predict air quality;
[0084] (5) Obtain continuous air quality forecast results based on iterative algorithms;
[0085] (6) Record the n...
