DeepAirNet: Applying Recurrent Networks for Air Quality Prediction

With the quick advancement of urbanization and industrialization, air pollution has become a serious issue in developing countries. Governments and natives have raised their increasing concern regarding air contamination since it influences human well-being and economic advancement around the world. Traditional air quality prediction methods depend on numerical data and require more computational power for the estimation of pollutant concentration and thus producing an unsatisfactory result. To tackle this problem, we applied widely used deep learning model. The pollutant considered for this work is Particulate Matter 10 (PM10). In this framework, Recurrent Neural Network (RNN), Long Short-Term Memory (LSTM), and Gated Recurrent Unit (GRU) are used for forecasting, based on the pollution and meteorological time series AirNet data. To figure out best architecture, we examined extensive analysis of different RNN models and its variations with its topologies and model parameters. Every experiment was run up to 1000 epochs by varying the learning rate in the range 0.01, 0.5. It is observed from the study that all the three models performed comparatively well in prediction.
