You are setting the decision threshold for a fraud detection model used on a payment platform. The model outputs a fraud score for each transaction, and anything above the threshold is blocked or sent for manual review. The team needs a threshold that catches enough fraud without creating too many false declines or review cases.
How would you decide on the right threshold for a fraud detection system?
