WebMay 25, 2016 · Now you can look at the ROC curve for each class individually. For each curve, the FRR indicates the rate how often samples of this class were predicted as samples of some other class, while the FAR indicates the rate how often a sample of some other class was predicted as a sample of this class: WebBiometric system classification using PCA and computing its FAR (False Accept Rate), FRR (False Reject Rate) and ROC (Receiver Operating Characteristics) using scikit-learn and …
WebSep 6, 2024 · One way to understand the ROC curve is that it describes a relationship between the model’s sensitivity (the true-positive rate or TPR) versus it’s specificity (described with respect to the false-positive rate: 1-FPR). Now, let’s disentangle each concept here. The TPR, known as the sensitivity of the model, is the ratio of correct ...
