Abstract
Background and Purpose: This study aims to forecast PM concentrations using four non-linear Machine Learning (ML) models.
Materials and Methods: The ML techniques employed include Light Gradient Boosting Machine (LGBM), Extreme Gradient Boosting Regressor (XGBR), Random Forest (RF), and Gradient Boosting Regressor (GBR). Meteorological and pollutant data were collected to predict the Air Quality Index (AQI) in Mashhad, Khorasan Razavi Province, Iran.
Results: Based on the MAE and MAPE metrics, RF demonstrated the best performance, while according to the MSE and RMSE metrics, GBR model was more robust.
Conclusion: This study proposes a high-accuracy PM prediction method using ML, which can be beneficial for global air quality monitoring and improving acute exposure assessments in epidemiological research.
