Fnr in machine learning
WebThe results were thoroughly analyzed using the true positive rate (TPR), false negative rate (FNR), positive predictive value (PPV), and false discovery rate (FDR) of the developed machine learning model, as presented in Table 4. Equation (2) can be used to compute TPR, FNR, PPV, FDR, and accuracy. WebNov 24, 2024 · True Positive Rate (tpr) = TP/TP+FN False Positive Rate (fpr) = FP/FP+TN The shaded region is the area under the curve (AUC). Mathematically the roc curve is the region between the origin and the coordinates (tpr,fpr). The higher the area under the curve, the better the performance of our model.

Thus to get the EER (the actual error rate) you could use the following: EER = fpr [np.nanargmin (np.absolute ( (fnr - fpr)))] as a sanity check the value should be close to EER = fnr [np.nanargmin (np.absolute ( (fnr - fpr)))] since this is an approximation.
