[Compute AUC of a ROC Function]
显示 更早的评论
Hi all,
I'm working to a classifier in which are presente 3 classes.
Now, I can plot ROC function through this:
figure, plotroc(targets,outputs)
h=gcf;
set(h, prop, valori);
print(h, '-dpdf', '-r300', strcat(folder_name,'\Roc.pdf'));
close all;
I would like to compute the AUC of this picture, Can you help me?
Thanks
Enrico

If you have Statistics Toolbox, the perfcurve function can compute AUC.
You mention that you have 3 classes. I am guessing this means you get 3 ROC curves. You can then compute 3 AUC values, one per curve.
