Learning objectives

  • Compare margin-based, distance-based, and probabilistic classifiers
  • Explain kernel intuition and why scaling matters for SVM and KNN
  • Choose fast baselines for text, tabular, and sparse-feature problems

Interview prompts

  • When would Naive Bayes beat a more flexible model?
  • Why is KNN sensitive to feature scaling and high-dimensional data?
