Fig. 7: Confusion matrix for a simple binary classifier.
From: Facial recognition as a tool to identify Roman emperors: towards a new methodology
As an example a simple binary classifier’s performance is measured here where the model correctly classifies eight out of ten images of Hadrian but also identifies two images as Lucius Verus. Same analysis applies to the class Lucius Verus. TP = True Positive. FP = False Positive. TN = True Negative. FN = False Negative.
