WebDec 11, 2014 · The ROC curve nicely illustrates the performance of our algorithm by plotting the true positive rate against the false positive rate as the discrimination threshold is varied. This way, in the process of characterizing the performance of our algorithm, we avert the need to specify the loss that we incur when a false positive versus a false negative occurs. WebDescription.
