Webdetection, researchers often report the partial area under the ROC curve (pAUC), typically over the range 0:01 and 1:0 false positives per image [1]. As the name implies, pAUC is calculated as the area under the ROC curve between two speciﬁed false positive rates (FPRs). It summarizes the practical performance of a detector and WebAFPR0 to summarize the partial area under an ROC curve in the interval (0,FPR0), i.e., when high speciﬁcity must be maintained. Moreover, the pAUC coincides with the entire area A(0,1) if the interval (0,1) is considered, and is null when the interval is reduced to a point. jll top citiesWebDownload scientific diagram -Receiver operating characteristics (ROC) curves with respective areas under the ROC curve of (A) central venous oxygen saturation (ScvO 2 ), (B) arterial lactate ... jll stock history
