Comparing Supervised and Unsupervised Learning in Physical Activity Research _ Next-Gen Research Techniques

🚀 Supervised learning predicts outcomes, while unsupervised learning uncovers hidden trends—but what happens when we combine them?
Machine learning is transforming physical activity research, but choosing the right approach can make all the difference.

This episode explores the differences between supervised and unsupervised learning in physical activity research, highlighting when to use each method and how they can be combined for more powerful analysis. Supervised learning excels at classifying activities and predicting health outcomes, while unsupervised learning reveals hidden patterns without predefined labels. We also discuss hybrid approaches like semi-supervised learning and reinforcement learning, which offer new possibilities for improving research accuracy and efficiency.
