DGMamba: Domain Generalization via Generalized State Space Model

1 code implementation11 Apr 2024 Shaocong Long, Qianyu Zhou, Xiangtai Li, Xuequan Lu, Chenhao Ying, Yuan Luo, Lizhuang Ma, Shuicheng Yan

SPR strives to encourage the model to concentrate more on objects rather than context, consisting of two designs: Prior-Free Scanning~(PFS), and Domain Context Interchange~(DCI).

Diverse Target and Contribution Scheduling for Domain Generalization

no code implementations28 Sep 2023 Shaocong Long, Qianyu Zhou, Chenhao Ying, Lizhuang Ma, Yuan Luo

In specific, DTS employs distinct soft labels as training targets to account for various feature distributions across domains and thereby mitigates the gradient conflicts, and DCB dynamically balances the contributions of source domains by ensuring a fair decline in losses of different source domains.
