Generation, augmentation, and alignment: A pseudo-source domain based method for source-free domain adaptation

no code implementations9 Sep 2021 Yuntao Du, Haiyang Yang, Mingcai Chen, Juan Jiang, Hongtao Luo, Chongjun Wang

The proposed method firstly generates and augments the pseudo-source domain, and then employs distribution alignment with four novel losses based on pseudo-label based strategy.
