Problem

Scenario

You're working on a supervised learning problem and need to decide which input features to create, transform, or exclude before training a model.

Question

How would you discuss feature engineering choices for a predictive model?

What This Tests

  • Choosing useful raw and derived features
  • Handling categorical variables, skew, and missingness
  • Avoiding leakage in time-based prediction
  • Using cross-validation and regularization to validate feature value
