Hi @ryoungj! Thanks for this outstanding work. I really appreciate your public code.
Recently, I am trying to reproduce the results of CAD (based on ResNet-50 backbone) in your paper. But I found a performance gap between this repo (83.5) and the domainbed repo (79.5) in PACS. In detail, for both repositories, I swept 40 hyper-params already. And in this repo, I use the run_sweep_e2e_domainbed.sh.
My questions are
Pls correct me if there is something wrong. Thank you so much.
Hello @ryoungj,
first of all, thank you for sharing your code! This is an amazing work!
I read your paper and I would start to replicate the results that you reported in Table 1.
In particular, I would replicate "CLIP S" (4th row).
If I correctly understood these numbers are obtained using as feature extractor the pre-trained CLIP model (Resnet-50). With the source features extracted from this pre-trained model, an MLP is trained with a supervised contrastive loss function.
So my questions are:
1 - Did I correctly understand CLIP S meaning?
2 - Why did you use a supervised contrastive loss function instead of a standard cross-entropy loss?
3 - How can I replicate these numbers using the code that you shared?
Thank you.
