前言: TP:True positive FP:False positive TN:True negative FN:False negative (从下文【解释1】中整理而来的图解) 上述四个名词广泛应用于各种领域。召回率(Recall),精确率(Precision),平均正确率(AP),交除并(IoU)是【object detection】领域的几个性能的衡量指... ...
calculate the TPR and FPR (= 1-TNR) for all possible thresholds. Use the class probability as predictor library(pROC) myRoc <- roc(response = model$pred$obs, predictor = model$pred$versicolor, positive = 'versicolor') # this is how the TPR and TNR rates over all pos...

FP (False Positive) – Thepositiveinstances that wereincorrectlyclassified. TN (True Negative) – Thenegativeinstances that werecorrectlyclassified. An easier way to represent this is with a table: True Positive Rate and Machine Learning True positive rate (TPR) is a performance metric used to eva...
