摘要： The present disclosure relates to a system for detecting an anomaly and a method for setting a threshold thereof. The method includes setting a minimum true positive rate (TPR) and a differentiation slope based on a user input, creating a receiver operating characteristic (ROC) curve using anomaly data and normal data, estimating a true negative rate (TNR) from the ROC curve based on the minimum TPR and the differentiation slope, and estimating and setting the threshold based on the estimated TNR.
