In a feature engineering case study, what is the role of domain knowledge?
Steps
Concepts
Step 1: Understand what domain knowledge means. It refers to the expertise and understanding of a specific field or industry.
Step 2: Recognize that in feature engineering, we need to select the right data (features) to use in our model.
Step 3: Realize that having domain knowledge helps us know which features are important and relevant to the problem we are solving.
Step 4: Identify that relevant features can improve the model's performance by making it more accurate and effective.
Step 5: Conclude that without domain knowledge, we might miss important features that could help our model succeed.
