Question 210
During risk sign-off, the team must assess this approved design step: Use logistic regression with calibrated probabilities as an interpretable binary-classification baseline. This relates to a situation where a lender needs a probability that an applicant will default, not a continuous estimated loan amount, and requires threshold-based risk decisions. Which limitation is most important when deciding whether this change is suitable?
- Available model licenses and required instance capacity differ by artifact.
- Sparse cold-start data and feedback loops can limit recommendation quality.
- Generic sentiment may miss sarcasm, specialized terminology, and unsupported languages.
- Logistic regression is not a time-to-default survival model and calibration must be checked.
Explanation
Correct Answer
D:This is a real operational limit for the described design: Logistic regression is not a time-to-default survival model and calibration must be checked.
