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 />
