hello,我用这个方法来对我自己的数据集进行分类,但是我的数据集相似性很高,是同一类别的图像,得到的效果很差,我想请教一下可以通过修改哪一部分来改善效果呀

理论上ImageNet-Dogs全是狗的图像,方法还是能够根据它的品种区分,或许您可以尝试根据数据集图片的特点改一下图像增广的方式

您好,我还想问一下,ImageNet-Dogs数据集样式您是怎样整理的

您好,可以参考 Yunfan-Li/Contrastive-Clustering#10

你是做reid的不,我有种感觉你是,reid数据集数据量少,而且相似度高,种类还多,单纯用这个方法效果肯定不好。那个dog的数据集能分出来是因为一共就10类,reid数据集动辄几百几千类,肯定不行。我建议你可以换个backbone,作者使用的backbone是随机初始化的,你换个好一点的backbone我感觉应该行
