The IMageNEt paper Image Net. presents the Average ROC curve for the 16 classes in the imagenet data, visit image figure. 8 in the paper. what is the known function to compute this ROC plot. As ROC plot is for a binary classification problem. Is this average ROC plot made in the picture average of ROC’s for all the 16 categories. Any Help would be appreciated.
I would guess it is using the one vs all approach. You measure the auc of the ROC on each class adding the probabilities of all other classes to create the other class. Then you average among classes the obtained areas under the curve.
