Problem

Scenario

You're training a supervised learning model and notice that training performance is strong, but validation performance is much weaker. You need to improve generalization without losing too much signal.

Question

How would you handle overfitting in a predictive model?

What This Tests

  • Diagnosing overfitting from train versus validation behavior
  • Using regularization to control model complexity
  • Applying cross-validation correctly
  • Tuning hyperparameters with the bias-variance tradeoff in mind
