accuracy 和 precision 的区别是什么? - 知乎
Precision = Prob( Y=1 | \\hat Y = 1 ) \\\\ 而让Precision的条件概率是基于模型的预测结果,而不是基于真实样本的。要知道预测结果 \\hat Y = 1 中可是混杂了正、负两种样本的。 而ROC曲线 …
精确率、召回率、F1 值、ROC、AUC 各自的优缺点是什么? - 知乎
F1-score 就是一个综合考虑precision和recall的metric: 2*precision*recall / (precision + recall) 基本上呢,问题就是如果你的两个模型,一个precision特别高,recall特别低,另一个recall特别 …
关于目标检测网络的召回率recall和精确率precision定义含义? - 知乎
您提到的两种计算recall和precision的方式都是合理的: 以IoU(Intersection over Union)为0.5作为阈值,统计TP、FP和FN,这种方式更简单直观。这在很多论文中被广泛采用,因为IoU=0.5被认为 …

为什么平均精准度(Average Precision,AP)就是PR曲线的线下面 …
即Precision=1,若AP是Precision的平均值,假设只有这一张图片,并且只有“people”这一个类别,则AP=1,mAP=1,这显然是灾难级的指标! 与Precision对应的还有Recall指标,其中文意 …

如何解释召回率与精确率? - 知乎
纠正下,精确率(precision)和准确率(accuracy)是不一样的,题主问的应该是精确率与召回率之间的差别。 一.定义辨析 刚开始接触这两个概念的时候总搞混,时间一长就记不清了。
