<![CDATA[This study explored the application of machine learning (ML) models and artificial neural networks (ANNs) in the assessment of public health concerns associated with air pollution. Utilizing a dataset comprising over 12,000 records from India and Nepal, encompassing both quantitative measurements and visual data, several classification models have been constructed and evaluated to predict air quality index (AQI) categories indicative of varying health risk levels. The implemented models comprise a decision tree (DT), support vector machine (SVM), random forest (RF), XGBoost, and deep neural networks (both convolutional and recurrent). The methodology entailed data preprocessing, feature significance analysis, and model assessment using accuracy metrics and ROC curves. The findings revealed a high classification accuracy across all models (>90%), with ensemble-based methods demonstrating enhanced performance. XGBoost attained superior accuracy with optimal resource efficiency; however, artificial neural network (ANN) models, particularly long short-term memory (LSTM), obtained accuracy levels of 98% by the 15th training epoch. Feature significance analysis revealed that AQI, PM2.5, and PM10 were the primary predictors of health risk categorization. Correlation analysis demonstrated robust associations between particulate matter measures (PM2.5, PM10), underscoring their significance in air quality evaluation. This study proposes a methodological framework for automating risk assessment procedures using machine learning approaches to facilitate more effective environmental health monitoring. The findings suggest that ensemble models offer an optimal balance between precision and computing efficiency for real-time air quality classification systems with potential applications in early warning systems and public health intervention techniques.]]>
