Calibration in Real-World Use Cases
When deploying machine learning models in the real world, having reliable probability estimates is crucial for many high-stakes applications. In credit scoring, lenders use models to estimate the likelihood that a customer will default on a loan. Here, calibrated probabilities inform not just the approval decision, but also the interest rate and credit limit. If a model predicts a 5% default probability, lenders expect that, among similar applicants, about 5 out of 100 will actually default.
In risk estimation, such as insurance underwriting, companies rely on models to set premiums and manage reserves. If the predicted risk is systematically too high or too low, insurers might set premiums that are uncompetitive or fail to cover actual claims. Fraud detection is another domain where calibrated models are essential. Banks and payment processors flag transactions as suspicious based on predicted fraud probabilities. If these probabilities are not well calibrated, too many false alarms can lead to customer frustration, while missed fraud can result in significant financial losses.
In high-stakes domains like healthcare, finance, and security, poor calibration can have severe consequences. Overconfident models may underestimate the true risk and lead to catastrophic decisions, such as approving risky loans or missing fraudulent transactions. Underconfident models can cause unnecessary interventions, lost revenue, or erosion of trust in automated systems.

2. In fraud detection, what is a key risk that arises from overconfident model predictions?
