WebFeb 25, 2024 · Definitions of TP, FP, TN, and FN. Let us understand the terminologies, which we are going to use very often in the understanding of ROC Curves as well: TP = True Positive – The model predicted the positive class correctly, to be a positive class. FP = False Positive – The model predicted the negative class incorrectly, to be a positive class.
