Figure 5
The figure contains two side-by-side ROC plots labeled “(a) R O C curve on M C S I dataset” and “(b) R O C curve on M S L D underscore V 2 dataset”. In both panels, the horizontal axis is labeled “False Positive Rate” and ranges from 0.0 to 1.0 in increments of 0.2. The vertical axis is labeled “True Positive Rate” and ranges from 0.0 to 1.0 in increments of 0.2. Each plot includes a dashed diagonal reference line from (0.0, 0.0) to (1.0, 1.0). Panel (a) shows four R O C curves with a legend listing A U C values: “Acne (A U C equals 0.96)”, “Chickenpox (A U C equals 0.87)”, “Monkeypox (A U C equals 0.96)”, and “Normal (A U C equals 0.99)”. The “Normal” curve rises vertically from (0, 0) to about (0, 1.0) and then runs along the top border near a true positive rate of 1.0. The “Monkeypox” curve rises quickly at low false positive rates, reaching about a 0.85–0.9 true positive rate near a false positive rate below 0.05, then increases to 1.0 by around a false positive rate of about 0.3. The “Acne” curve increases in several steps, starting near a true positive rate of about 0.4 at a false positive rate near 0.02, reaching about 0.8 near 0.06, and reaching 1.0 by around a false positive rate of about 0.2. The “Chickenpox” curve rises more gradually, with multiple steps from about a 0.5 true positive rate near a false positive rate around 0.02, reaching about 0.8 near 0.3, and approaching 1.0 by around a false positive rate near 0.6. Panel (b) shows six R O C curves with legend entries: “Chickenpox (A U C equals 0.93)”, “Cowpox (A U C equals 0.98)”, “H F M D (A U C equals 0.99)”, “Healthy (A U C equals 0.99)”, “Measles (A U C equals 0.88)”, and “Monkeypox (A U C equals 0.92)”. The “Healthy” curve rises steeply to near the top-left corner, reaching about a true positive rate of 0.9 at a false positive rate below 0.05, then reaches 1.0 by roughly a false positive rate near 0.1 and stays along the top border. The “H F M D” curve also rises quickly, reaching about 0.9 true positive rate at a false positive rate below 0.05 and approaching 1.0 by around 0.1. The “Cowpox” curve increases sharply at low false positive rates, reaching roughly 0.9 by about 0.05 and nearing 1.0 by around 0.1–0.15. The “Chickenpox” curve rises in larger steps, reaching about 0.75 at a false positive rate near 0.02, about 0.9 around 0.15–0.2, and reaching 1.0 by roughly 0.35. The “Measles” curve rises early to about 0.65–0.7 near a false positive rate close to 0.02, then stays around 0.88–0.9 across much of the plot before rising to 1.0 near the far right edge. The “Monkeypox” curve rises from low false positive rates to about 0.65 near 0.05, then increases to about 0.9 near 0.1, and remains high (around 0.95) through most of the plot before reaching 1.0 close to a false positive rate near 0.8–0.85.
