看到您在这块对于background 类好像采取了和unknown类一样的操作,可以解释一下这个的原因吗?论文中好像没有看到相关的阐述。
The text was updated successfully, but these errors were encountered:
We select the same number of background samples to 1) balance foreground and background samples, 2) recall unknown from background.
Sorry, something went wrong.
您好,我想问一下这里的self.num_class是know_class+unknow_class+bg嘛 我看到代码分类训练是是self.cls_score = nn.Linear( self.cls_score.in_features, self.num_classes + 1, bias=False)不太明白未知类的概率是怎么得到的。 感谢
