你好。Graph Sampling(GS)本身并不是专门针对Domain Generalization(DG)提出来的,它需要结合一个DG算法。这里边DG效果好主要还是因为QAConv。在此基础上,GS对QAConv的提升主要是两个方面,一个是去掉了class memory,训练速度大幅提升了;另一方面是采样了更多困难样本后,模型的鉴别能力提升了,在已有的DG模型的基础上。

谢谢;因为我的实验里,只在原模型(OSNet)的基础上,把原本的PK sampler改成Graph Sampler之后,跨数据集测试的性能也有较明显的提升,所以觉得好像Graph Sampling这个模块对domain generalization也是有效果的。

是的,主要是对训练时模型鉴别能力的提升,但前提还是需要有个本身DG性能还不错的模型,OSNet是可以的。

可以麻烦分享一下OSNet-IBN-GS的代码吗? @Terminator8758 @ShengcaiLiao ,谢谢两位老师!
