Other Curves<br />
Other research communities have produced and<br />
used graphical <strong>evaluation</strong> techniques similar to<br />
ROC Curves.<br />
Lift charts plot the number <strong>of</strong> true positives versus the overall<br />
number <strong>of</strong> examples in the data sets that was considered for the<br />
specific true positive number on the vertical axis.<br />
PR curves plot the precision as a function <strong>of</strong> its recall.<br />
DET curves are like ROC curves, but plot the FNR rather than<br />
the TPR on the vertical axis. They are also typically log-‐scaled.<br />
Relative Superiority Graphs are more akin to Cost-‐Curves as<br />
they consider costs. They map the ratios <strong>of</strong> costs into the [0,1]<br />
interval.<br />
