Questions & Step-by-Step Solutions

What does the term 'feature engineering' refer to?
Correct Answer: Feature engineering ka matlab hai naye input features banana existing data se taaki model ki performance behtar ho sake.
  • 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.
  • Feature Engineering – The process of using domain knowledge to create new input features from existing data to enhance the performance of machine learning models.
