Abstract

The growing events of air pollution over the last decade have made implementing preventative measures a need more than a caution. An effective air quality forecasting system is the backbone of all measures. A detailed global literature review identifies statistical and ensemble models to be more efficient for forecasting problems. This study aims at experimentally analyzing 10 machine learning models on predicting PM2.5, PM10, SO2, CO, NO2 and O3 for developing a custom air quality forecaster for Delhi, India. The performance of all models was compared individually for each pollutant prediction using evaluation metrics, such as RMSE, MAE and MedAE. Based on experimental evidence, we conclude that a timeseries based deep neural network model performs best in the given scenario and can be explored further to create a custom air quality forecasting framework.
