What is a threshold in a Precision-Recall curve?

September 23, 2023 by Tarik

ROC Curves: x-axis: False Positive Rate FPR = FP /(FP + TN) = FP / N y-axis: True Positive Rate TPR = Recall = TP /(TP + FN) = TP / P Precision-Recall Curves: x-axis: Recall = TP / (TP + FN) = TP / P = TPR y-axis: Precision = TP / (TP + … Read more

F1 Score vs ROC AUC

March 9, 2023 by Tarik

Introduction As a rule of thumb, every time you want to compare ROC AUC vs F1 Score, think about it as if you are comparing your model performance based on: [Sensitivity vs (1-Specificity)] VS [Precision vs Recall] Note that Sensitivity is the Recall (they are the same exact metric). Now we need to understand what … Read more
