感谢作者分享,我使用您实现的模型在我自己的数据集上训练,并且使用您提供的评估指令,评估了模型。我得到的表格在下面。请问F1 score和iou值完全相同,这是否是正常的

不好意思,我没表述清楚。我是想实现一个二分类任务,只有前景和背景。我得到的结果是下面这样的。请问红色框的内容一样是否正常?以及黄色框中的四个结果分别对应什么?十分感谢!

Hi,

That is the field of ratio which means the ratio of two categories, it is computed from the ground truth and is deserved to be same, if your test set is fixed.

正如“CoinCheung”所说,红色框里的是比例,是由你的测试集/验证集决定的。ss是单尺度,ssc是单尺度裁剪,msf是多尺度翻转,msfc是多尺度翻转+裁剪。ss\ssc\msf\msfc分别计算了f1 score和iou。
