AdaEmbed: Semi-supervised Domain Adaptation in the Embedding Space

no code implementations23 Jan 2024 Ali Mottaghi, Mohammad Abdullah Jamal, Serena Yeung, Omid Mohareri

Our method's effectiveness is validated through extensive experiments on benchmark datasets such as DomainNet, Office-Home, and VisDA-C, where AdaEmbed consistently outperforms all the baselines, setting a new state of the art for SSDA.
