Solution:

Cross-validation is a model evaluation technique, not a feature engineering technique.

Which of the following is NOT a common technique in feature engineering?

Which of the following is NOT a common technique in feature engineering?

Step 1: Understand what feature engineering is. It involves creating new features or modifying existing ones to improve model performance.
Step 2: Identify common techniques in feature engineering, such as normalization, encoding categorical variables, and creating interaction features.
Step 3: Recognize that cross-validation is a method used to evaluate how well a model performs, not to create or modify features.
Step 4: Conclude that since cross-validation does not involve changing or creating features, it is NOT a common technique in feature engineering.
