3. Informed Data Preprocessing

• Data Cleaning and Transformation: Knowing which data patterns or trends are typical for the domain allows practitioners to decide whether to retain, correct, or discard certain data points. For example, a domain expert in meteorology may know which weather outliers should be kept as significant events and which to clean as sensor errors.
• Handling Missing Data: Domain expertise aids in deciding how to treat missing data. For instance, missing values in a medical dataset could indicate a “not applicable” situation rather than an error, a nuance that domain experts understand well.

4. Algorithm and Model Selection

• Choosing Appropriate Models: Certain domains have specific requirements that influence algorithm selection. In finance, for example, explain-ability is often essential, so simpler models like decision trees or linear regression might be preferred over complex neural networks.
• Defining Constraints and Boundaries: Understanding the domain helps in setting realistic model boundaries, constraints, and assumptions. For instance, in manufacturing, models must consider safety and operational constraints that might not be immediately apparent without industry knowledge.

5. Feature Engineering and Contextual Transformations

• Creating Domain-Specific Features: Domain knowledge is essential for deriving new features that provide insights specific to the domain. For example, in retail, calculating customer lifetime value (CLV) from transactional data requires understanding purchase frequency, average spend, and retention rate.
