Example: Feature Engineering in Credit Scoring
To illustrate the practical impact of feature engineering, consider a credit scoring application. Raw customer data (e.g., age, income, loan amount) can be transformed into richer features:
- Debt-to-Income Ratio: Calculated as total debt divided by total income, providing a relative measure of financial burden.
- Credit Utilization Rate: Indicates the percentage of available credit the customer is using.
- Account Age: Time since opening the oldest credit account, showing credit history depth.
- Recent Delinquencies: Frequency count of late payments in the last year.
By engineering these features, the predictive model can more accurately assess credit risk, leading to better lending decisions and reduced default rates.
