Goal: Classify human activities (e.g., Walking, Sitting,
Standing) using smartphone sensor data.
• Why It Matters: Helps in health monitoring, fitness apps,
and smart devices.
• Approach: Use PCA to reduce data dimensions and
Random Forest to classify activities.
“Our problem is to classify activities like walking or sitting
using sensor data from smartphones. This is useful for apps
that track fitness or monitor health. We’ll use PCA to
simplify the data and Random Forest to predict activities.”
