During a model quality incident, a fraud classifier reports 99% accuracy but catches only 18% of confirmed fraud cases. Fraud is less than 1% of transactions. What is the best next modeling response?

Choose the Best Answer

Review recall, precision, and mitigation choices against fraud costs. Keep the model because high accuracy is enough for rare-event detection. Convert the fraud label to a continuous amount and train a regression model. Remove all legitimate transactions from evaluation so every remaining prediction is fraud.
