Splet我们得到了一个2x2的矩阵，这是什么意思？建议先去看看本文最开始的那篇文章。 在二分类的模型中，混淆矩阵把预测情况与实际情况的所有结果进行组合，形成了真正 (true positive)、假正 (false positive)、真负 (true negative) 和假负 (false negative) 四种情形，分别由TP、FP、TN、FN 表示（T代表预测正确，F ... SpletSensitivity depends on TP and FN which are in the same column of the confusion matrix, and similarly, the specificity metric depends on TN and FP which are in the same column; …

Splet05. apr. 2016 · ROC curves plot TPR vs. FPR and vary the thresholds based on the rank order of the probabilities of the training set. The threshold that is picked is the probability associated with the point in the top left hand most corner. That basically maximizes the TPR and minimizes the false positive rate. SpletSensitivity and specificity mathematically describe the accuracy of a test which reports the presence or absence of a condition. If individuals who have the condition are considered "positive" and those who don't are considered "negative", then sensitivity is a measure of how well a test can identify true positives and specificity is a measure of how well a test … eyewear west seattle
