Supplementary: Subsidiary Prototype Alignment for Universal Domain Adaptation

In this appendix, we provide more details of our approach, extensive implementation details, additional analyses, limitations and potential negative societal impact. We summarize the notations used throughout the paper in Table 1. The proposed approach may be unsuitable for datasets with very less number of classes. This might make technology more accessible to organizations and individuals with limited resources. It can also aid applications where data is protected by privacy regulations and hence difficult to collect.
