Comparison of the tests S2/S2 and S4/S2 (darker and lighter histograms) run with the VGG-like network (top), the IncNet (center), and the ResNet (bottom). In each panel, we show the results for the different metrics. From left to right, we show the precision on the class of the nonlenses (P₀) and lenses (P₁), the recall on the class of the nonlenses (R₀) and lenses (R₁), the F1-score on the class of the nonlenses (F1₀) and lenses (F1₁), and the overall accuracy (A).
