The sensitivity, specificity, positive predictive values (PPV) and negative predictive values (NPV), and false positive rates (FPR) and false negative rates (FNR
) of preoperative sampling histological diagnosis when compared to hysterectomy findings as gold standard were 58.3%, 90%, 70%, 81.8%, 30.1%, and 18.2% (Table 2).
The lower the values of ME, FPR, and FNR
, the better the segmentation.
New Delhi [India], May 7 ( ANI ): As a part of Walking the Naga initiative, members of the Forum for Naga Reconciliation (FNR
) reached out to the Naga community residing in New Delhi.
Based on these measurement elements, the accuracy (ACC), precision rate (PR), recall rate (RR), F-Measure, FPR, and FNR
are applied to evaluate the performance of the fusion techniques.
In addition, the true-positive rate TPR (the percentage of positive instances correctly classified), the false-positive rate FPR (the percentage of negative instances misclassified), the false-negative rate FNR
(the percentage of positive instances misclassified), and the true-negative rate TNR (the percentage of negative instances correctly classified) are also widely employed.
DHFR can be found in human and Plasmodium, but FNR
is found only in Plasmodium.
Figures 2 and 3 and Tables A10 and A11 also showed that the gs method had significantly smaller FPR and FNR
than the other 16 methods, except that the gs method had significantly higher median FNR
in SimI (Figure 2).

Accuracy, TPR, TNR, FPR and FNR
Equations Accuracy = (TP + TN) / (TP + FN + FP + TN) TPR=TP/(TP + FN) TNR=TN/(FP + TN) FNR
=FN / (TP + FN) FPR=FP/(FP + TN) - FP: total number of false positive - TP: total number of true positive - FN: total number of false negative - TN: total number of true negative Figure 7 shows the main equations of accuracy, TNR, TPR, FPR, and FNR
Therefore, there were initial major concerns about the false-negative rate (FNR
) and the feasibility and reliability of SLNB after NACT.
(Note that there are also the terms False Positive Rate, which is l-[Specificity], and False Negative Rate, which is l-[Sensitivity]; strictly speaking, then, the FPR [false positive rate] could stand in for specificity, and the FNR
[false negative rate] for sensitivity in our ability to fully appreciate the performance reliability of an assay).
