i plotted the ROC curve for RandomForest Classifier and this is what i get :

enter image description here

The shape looks weird to me , can somebody help me to make sense of it , and is this shape 'common' to not say normal?

thank you.


Imagine you have a blue line drawn from the point (0,0) to the point (0, 0.51). Do you see a common shape now?

That happens because you have few or no predicted probabilities above 0.9 or something close to it, so the point with 0 false positives is never touched.

The ROC curve you are watching is perfectly normal.
