The Air Quality Index (AQI) dataset contains information on measurements of pollutants and ambient air quality conditions at certain location that can be used to predict quality. Unfortunately, this often has many missing observations imbalanced classes. Both these problems affect the performance prediction model. In particular, predictions for minority class are very important because inaccura...
Owing to climate change, industrial pollution, and population gathering, the air quality status in many places China is not optimal. The continuous deterioration of air-quality conditions has considerably affected economic development health China’s people. However, diversity complexity factors which affect pollution render monitoring data complex nonlinear. To improve accuracy prediction index...
