Appendix A Experimental Details

This is referred to as DOC-Feat in [24]. COT uses the empirical estimator of the Earth Mover's Distance between labels from the source domain and softmax outputs of samples from the target A.2 Dataset Details In this section, we provide additional details about the datasets used in our benchmark study. Overall, we obtain 5 datasets (i.e., CIFAR10v1, CIF AR100 Similar to CIFAR10, we use the original CIFAR100 set as the source dataset. Overall, we obtain 3 different domains. Overall, we obtain 3 different domains.
