Your question is Reducing Overfitting in ML Models. Take a moment with it on the right.

Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).

Problem

You are training a supervised learning model and the training score is much better than the validation score. The model looks strong in development, but it may not generalize well to new data.

Question

How would you handle overfitting in a machine learning model?

What to Look For

  • Large gap between training and validation performance
  • Validation score drops as model complexity increases
  • Instability across cross-validation folds
  • Sensitivity to noisy or high-cardinality features
