You're given a dataset with several features, some of which are highly correlated. How would you handle this using dimensionality reduction techniques?

  • Applying K-Means Clustering
  • Applying L1 Regularization
  • Applying Principal Component Analysis (PCA)
  • Applying Random Forest
Principal Component Analysis (PCA) would be used to handle high correlation among features. It reduces dimensionality by creating new uncorrelated variables that capture the variance present in the original features.
