Application of Decision Tree C4.5 Algorithm in Air Quality Evaluation

Abstract

Air pollution has a significant impact on human production and life, the prediction of air quality's level is conducive to the relevant departments to take appropriate measures.This paper selects six basic pollutants PM10,PM2.5,SO 2 ,NO 2 ,CO and O 3 , which are stipulated in the "Ambient Air Quality Standard" (GB3905-2012) issued by China in 2012.Based on the data of air pollutant concentration in Wuhan in October, 2016, a prediction model of air quality grade based on C4.5 decision tree algorithm was established.The experimental results show that the proposed algorithm has an ideal classification prediction effect.
