Air Quality Prediction Using Deep Learning Techniques
Summary
Accurate forecasting of ambient pollutant concentrations is critical for public health, urban planning and policy intervention. Traditional statistical and deterministic models often struggle to capture the complex, non-linear and spatiotemporal dynamics of air pollution. In recent years, deep learning has emerged as a powerful approach to model these dynamics by learning hierarchical representations from large, multi-source datasets that include ground-station readings, meteorological variables and satellite observations. Architectures such as convolutional neural networks extract spatial features from pollution maps, while recurrent networks—especially long short-term memory layers—encode temporal dependencies in pollutant time series. Hybrid models further enhance performance by combining autoencoders for feature compression with sequence models for prediction. Advances in transfer learning, attention mechanisms and graph neural networks have enabled more robust forecasts across regions with sparse monitoring, improving anticipation of peak pollution events and informing early warning systems.
