IEEE/ICACT20220012 Question.1 Questioner: spcho@hanmail.net 2022-02-15 오후 11:47:33	IEEE/ICACT20220012 Answer.1 Answer by Auhor patrick.hosein@sta.uwi.edu 2022-02-15 오후 11:47:33
Can you explain in the procedure how you defined TP, TN, FP, and FN in the CTRT model?	A True Positive (TP) is a call flagged as fraud that is actually fraud, while a True Negative (TN) is a call flagged as legitimate that is actually legitimate. A False Positive (FP) is a legitimate call flagged as fraud, which can result in poor customer service if the is incorrectly terminated. A False Negative (FN) error is a fraudulent call flagged as legitimate, which can lead to revenue leakage for the company. In our model, we attached a cost of 1 to a FN error and 0.1 to a FP error.
