The graph showcases the relationship between sensitivity and specificity in a two-dimensional coordinate system. The x-axis denotes specificity, ranging from zero to one, while the y-axis represents sensitivity, also from zero to one. A red line demonstrates the sensitivity at various levels of specificity, starting at the origin and rising sharply, indicating improved sensitivity at increasing specificity values. An additional diagonal line, usually representing a baseline classifier, extends from the lower left to the upper right of the graph, highlighting the trade-off between sensitivity and specificity.ROC curve – validation set
