Hey everyone,

I'm fairly new to data mining and RapidMiner and I just have a quick question about the AUC plot (or the ROC curve)

When I run a X-validation for a binomial classification problem, and output my performance using the binomial classification performance operator, I output  several performance including the ROC curve. However, the ROC in RapidMiner also provides a blue threshold line along with the typical curve.

Can anyone explain what the threshold line means and how to interpret it. If you have any documentation on this that would also be great.

Thank you in advance!  Smiley
