An introduction to ROC analysis - CCRMA

receiver operating characteristics (ROC) graph is atechnique for visualizing organizing and selecting classi?-ers based on their performance ROC graphs have longbeen used in signal detection theory to depict the tradeo?between hit rates and false alarm rates of classi?ers (Egan1975; Swets et al 2000)

Which two points in ROC space have the same performance?

Two pointsin ROC space, (FP1,TP1) and (FP2,TP2), have the sameperformance if This equation de?nes the slope of an iso-performance line.All classi?ers corresponding to points on a line of slopemhave the same expected cost. Each set of class and cost dis-tributions de?nes a family of iso-performance lines.

How ROC analysis is used in med algorithm 4?

ROC analysis is commonly employed in med- Algorithm 4.TThreshold averaging of ROC curvesInputs: samples, the number of threshold samples;nrocs,the number of ROC curves to be sampled;ROCS[nrocs], anarray ofnrocsROC curves sorted by score;npts[m], thenumber of points in ROC curvem.

How to generate ROC points?

Algorithm 1.E?cient method for generating ROC pointsInputs: L, the set of test examples;f(i), the probabilisticclassi?ers estimate that exampleiis positive;PandN, thenumber of positive and negative examples. Fig. 6. The optimistic, pessimistic and expected ROC segments resultingfrom a sequence of 10 equally scored instances.

What is a ROC curve?

An ROC curve is a two-dimensional depiction of classi-?er performance. To compare classi?ers we may want toreduce ROC performance to a single scalar value represent-ing expected performance. A common method is to calcu-late the area under the ROC curve, abbreviated AUC (Bradley, 1997; Hanley and McNeil, 1982). Since the
