Q: What does the term 'feature engineering' refer to?
Solution: Feature engineering involves creating new input features from existing data to improve model performance.
Steps: 4
Step 1: Understand that features are the pieces of information used by a model to make predictions.
Step 2: Realize that feature engineering is the process of taking existing data and transforming it into new features.
Step 3: Know that the goal of feature engineering is to improve how well a model can learn and make accurate predictions.
Step 4: Examples of feature engineering include combining two features into one, creating a new feature based on calculations, or converting data types.
