- 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。
- 关于目标检测网络的召回率recall和精确率precision定义含义? - 知乎
关于目标检测网络的召回率recall和精确率precision定义含义? YOLOv5源码中评价模型的recall和precision计算是通过pr曲线上F1值最大点对应的p和r实现的;而我所看的论文中对p和r进行评价基本是…
- 如何解释召回率与精确率? - 知乎
一般来说,Precision就是检索出来的条目(比如:文档、网页等)有多少是准确的,Recall就是所有准确的条目有多少被检索出来了。 正确率、召回率和 F 值是在鱼龙混杂的环境中,选出目标的重要评价指标。 不妨看看这些指标的定义先: 1
- Red Dot For Rimfire Precision Bullseye - migunowners. org
Red Dot For Rimfire Precision Bullseye I have been shooting Rimfire precision bullseye for a couple of months now using my MK IV with a RMR red dot Most others are using the tube style red dots I think all of the top guy’s use the tube style sight So, I started doing a little research online and haven’t found any definitive answers

- 为什么平均精准度(Average Precision,AP)就是PR曲线的线下面积?
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
- 特征点匹配的precision和recall是如何计算的? - 知乎
特征点匹配的precision和recall是如何计算的? 最近一直在研究特征提取与匹配方面的问题,看了一些相关文献,发现普遍是采用了计算precision和recall的曲线作为评价标准,但是大部分文章并未说… 显示全部 关注者 7
