在论文中讨论Known Object Detection的时候,提到了"sacrifice the close-set performance for the openset detection, leading to large performance drops in Known-mAP across four tasks",请问有什么办法可以缓解这种已知类的mAP下降吗?目前我遇到了这个问题,期待您的回复.

以我的经验,一般这种情况都是未知类目标的伪标签质量的问题,比如:一个bounding box可能并没有框中有意义的东西;或者把背景区域作为未知类伪标签。不知道你用的是具体哪一种OWOD方案,但你可以在tensorboard里面看看,在训练过程中到底哪一些区域被标记为未知类目标。
