WebOct 18, 2013 · (B) Shuffled AUC scores of these models. The important point here is that the annotation map scores significantly above chance (i.e., AUC and Shuffled AUC of a random map are both equal to 0.5). AM model performs as well as the ITTI98 model. Note that the shuffled AUC values are smaller than AUC values due to discounting central bias in data.
