Abstract

The Air Quality Index (AQI) must be accurately and highly evaluated to limit the effects when exposed to air pollution on individual health and the ecosystem. The traditional techniques are used to predict air quality ineffective in managing the nature of the environmental data being analyzed and minimizing the effects of the most significant features of large numbers of dimensions. The purpose of this work is to address these issues using the creation of a hybrid deep learning algorithm implementing Feature Selection Techniques, Recurrent Neural Networks and a Quantum-Inspired Genetic Algorithm (QIGA).  The eXtreme Gradient Boosting (XGBoost) will be applied to the environmental dataset to evaluate importance of features. Additionally, the Principal Component Analysis (PCA) will reduce the dataset's dimensionality using most significant features from the original dataset as inputs for the prediction model. Recurrent Neural Networks (RNNs) are able to detect time-variant patterns of air quality (i.e., the pattern changes over time) based on the use of controlled memory. The use of quantum-based methodologies will allow rapid searches over high-dimensional datasets resulting higher performance than traditional optimization methods. This innovative methodology will lead to improved accuracy, computational efficiency and interpretability of AQI predictions. This method will be the basis for smart environmental monitoring systems used by researchers, policymakers and urban planners to make innovative decisions. Finally, the flexibility of the system makes it possible for users to apply it in any other forecasting-based environmental issues showing the scalability and efficiency.
