Probabilities of the second network. These probabilities are representing the certainity of the network that an image is EARL1 compliant. If the probability is below 0.6 for an EARL2 compliant image, the image is still correctly classified. The network can identify EARL1 reconstructions very well why it has more difficulties with identifying EARL2 compliant images. As can be seen, by setting the threshold to separate these two reconstructions to 0.6 the overall accuracy increases
