- accuracy 和 precision 的区别是什么？ - 知乎
precision的一般应用场景是，还是那个电子称，称千克原器，告诉你重0吨，上面的数字显示也只有吨（当然真实的电子称不会这么夸张），你又放了999个上去，告诉你是1吨。 这称可以说是precision不好。
- 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特别高，precision特别低的时候，f1-score可能是差不多的，你也不能基于此来作出选择。

阐述完Precision和Recall的计算方式后，介绍一下PR (Precision-Recall)曲线，PR (Precision-Recall)曲线可以反映一个算法的性能，其绘制的方法通俗来说就是：先设定一个较高的阈值θ（目标检测里通常用IOU，比如首先设定IOU≥0 9，则认定该预测是true，否则为false），然后
