This study investigates several machine and deep learning models to predict the concentrations of PM2.5 and PM10 particles in the air of Tashkent city. These particulate matters are the most influential factors in Tashkent’s high air quality index. The dataset utilized in this investigation comprises PM2.5 and PM10 concentration levels alongside meteorological indicators, including temperature, humidity, wind speed, and air pressure, gathered from 16 monitoring stations around Tashkent city and accessible at https://opendata.tashkent.uz/. The algorithms, Linear Regression (LR), Random Forest (RF), Support Vector Regression (SVR) and Gated Recurrent Unit (GRU) neural network were used to build predictive models on the concentrations of particles PM2.5 and PM10. The model performances were evaluated using metrics RMSE, MAE, MAPE, R2 and compared. The results show that the GRU and RF models performed significantly better than LR and SVR with R² values of 0.98 and 0.97, respectively, compared to the value of 0.91 and 0.93 respectively, achieved by LR and SVR. The GRU model was evaluated as the most effective approach due to its ability to deeply explore dynamic relationships across time series.
