Abstract

This study explores the application of machine learning models for classifying physical activities using biometric measures and personality traits. A dataset from Figshare, integrated with survey responses, was analyzed using two algorithms: Gradient Boosting and a Tuned Stacking Classifier. Gradient Boosting achieved the highest accuracy at 73%, while the Stacking Classifier demonstrated balanced performance across all metrics, achieving 72% and effectively addressing class imbalances. The study highlights the models’ real-world applicability through validation and visualization using a Tableau dashboard. Key predictors included Resting Heart Rate, Honesty-Humility personality trait, and BMI. Challenges such as class imbalance were addressed using SMOTE and imputation techniques. The findings emphasize the potential of machine learning in personalized health monitoring and promoting active lifestyles via wearable devices.
