Supplementary Material A Dataset Detail

Since DSLR and Webcam do not have many examples, we conduct experiments on D to A, W to A, A to C (Caltech), D to C, and W to C shifts. The setting is the same as (11). The second benchmark dataset is OfficeHome (OH) (12), which contains four domains and 65 classes. The third dataset is VisDA (9), which contains 12 classes from the two domains, synthetic and real images. The synthetic domain consists of 152,397 synthetic 2D renderings of 3D objects and the real domain consists of 55,388 real images.
