Figure 5. ROC curve (AUROC = 0.89) for the trained ANN (4∶3∶3∶1).

Figure 5

As shown in this Figure, the optimal sensitivity and specificity of the ANN are calculated at the half angle and ROC curve intercept point (Point Opt.; Specificity Optimal  = 0.84, Sensitivity Optimal = 0.85) which implies that the ANN can predict lesion and tissue with a sensitivity of 85% and a specificity of the 84%.
