Leveraging Geospatial Intelligence
Earth Observation (EO) data, particularly from Sentinel-2, plays a crucial role in understanding environmental conditions like climate change, floods, and infrastructure development. Integrated with remote sensing databases (Landsat, MODIS), EO provides spatial, temporal, and spectral measures vital for analyzing environmental ecosystem changes relevant to healthcare. This information aids in pollution control, disease prevention, and climate change impact assessment, forming a critical base for public health welfare systems.
Advanced Predictive Modeling
The study evaluates various Machine Learning (ML) algorithms for predicting health outcomes, including Multiple Linear Regression, Polynomial Regression, kNN Regression, Support Vector Regression (SVR), and Random Forest Regression (RFR). RFR demonstrated superior performance, achieving a 99.31% R² with normalized data, indicating its robustness. The research emphasizes the importance of ensemble training models and notes the role of data normalization in enhancing accuracy, especially for kNN.
Targeting Critical Public Health Challenges
The primary focus is the prediction of anxiety, a significant health concern, especially post-COVID. Beyond anxiety, the model targets other critical outcomes such as diabetes, hypertension, depression, asthma, and opioid-related issues. This predictive capability is vital for policymakers and medical institutions, enabling proactive interventions for social well-being. Future work aims to integrate the Drug Bank dataset to anticipate specific prescriptions based on predicted outcomes.
Ensuring Data Quality and Efficacy
Effective data preprocessing is fundamental for accurate ML model performance. This involves crucial steps like removing noisy data, handling 15% missing values (particularly in environmental features like temperature and radiation, and sociodemographic like net annual income), and addressing outliers (e.g., extreme solar radiation values). Data integration combines 102 sociodemographic, 39 environmental, and 11 satellite features, followed by transformation and reduction (e.g., age categories to broader groups) to optimize the dataset for machine learning.
