预测中,前68个样本中有11个被预测为了1类别,后32个样本中有8个被预测为了0类别。 那么我们先说分类报告中最右边的support为什么是68和32。 support意思为支持,也就是说真实结果中有多少是该类别。那么有68个为0类别,32个为1类别。 在左边的召回率里,分母为support个数。 那么0类别里召回率即recall的计算为: ...
classification report 使用 别人写的,但是还是有些不清晰,我最后补上了 最后一行:第一个0.7=(0.5*1+0*1+1*3)/5 其他类似 support行:在真实数据中y_ture中class 0有一个 class 1有1个 class 2有3个

混淆矩阵的分类报告(classification report)是基于混淆矩阵计算出的一种评估分类模型性能的指标报告。它通常包含以下几个指标: 准确率(Precision):表示模型预测为正例的样本中,真正例的比例,即 TP / (TP + FP)。准确率高表示模型预测为正例的样本中真正例的比例较高。
在多分类的时候,用sklearn的classification_report会发现有的会打印出micro avg,有的则是accuracy。 例子展示 例子1 y_pred = [1, 1, 2] y_true = [1, 1, 1] print(classification_report(y_true, y_pred, labels=[1, 2])) precision recall f1-score support 1 1.00 0.67 0.80 3 2 0.00 0.00...
