Domain knowledge is subject-matter understanding that guides feature engineering: it helps turn raw financial data into variables that represent meaningful concepts rather than arbitrary correlations. In a data asset layer, it supports preparing data for predictive modeling alongside attention to data quality, security, and regulatory compliance. section 1.4.1
Financial examples of domain-guided features include:
- Volatility measures for investment signals. section 1.4.1
- Velocity-based variables for fraud detection. section 1.4.1
- Seasonal patterns in consumer spending. section 1.4.1
