Air quality classification in Thailand based on decision tree

The paper presents a model for management classifier air quality by algorithm of decision tree using air quality index in Thailand including a pollutant´s concentration e.g. O₃, NO₂, CO, SO₂, PM₁₀ and levels of healthy concern. The purpose of this research is to establish rules of separated air quality classification by levels of healthy concern. The results of this study are correctly classified into instances of training set of 96.80% and testing set of 91.07%. The ROC curve shows that the training set data and testing set data are similar to such results. The algorithm of decision tree can use to become rules of separated air quality classification by levels of healthy concern.
