A risk minimization framework for domain adaptation

Bo Long, Sudarshan Lamkhede, Srinivas Vadrevu, Ya Zhang, Belle Tseng
2009 Proceeding of the 18th ACM conference on Information and knowledge management - CIKM '09  
A novel learning framework, Domain Transfer Risk Minimization (DTRM), is proposed based on this concept.  ...  DTRM simultaneously minimizes the empirical risk for the target and the regularized empirical risk for source domain.  ...  Based on the concept of the label-relation function, we propose a new framework, Domain Transfer Risk Minimization (DTRM), for domain adaptation.  ...

Contradictory Structure Learning for Semi-supervised Domain Adaptation [article]

Can Qin, Lichen Wang, Qianqian Ma, Yu Yin, Huan Wang, Yun Fu
2021 arXiv   pre-print
To solve these challenges, we propose a novel framework for semi-supervised domain adaptation by unifying the learning of opposite structures (UODA).  ...  UODA consists of a generator and two classifiers (i.e., the source-scattering classifier and the target-clustering classifier), which are trained for contradictory purposes.  ...  The task losses of the two domains are summed for empirical risk minimization: Θ * G = arg min Θ G L src + L tar − βH src + λH tar . (9) The whole framework is trained in an end-to-end manner with the  ...

Adaptive Domain Generalization via Online Disagreement Minimization [article]

Xin Zhang, Ying-Cong Chen
2022 arXiv   pre-print
Unlike previous DG works that stake on a static source model to be hopefully a universal one, our proposed AdaODM adaptively modifies the source model at test time for different target domains.  ...  Although various DG approaches have been proposed, a recent study named DomainBed, reveals that most of them do not beat the simple Empirical Risk Minimization (ERM).  ...  It is worth noting that our algorithm is a general framework which could be implemented on most existing DG methods. We show case on the vanilla Empirical Risk Minimization (ERM). A.  ...

Entropy Minimization vs. Diversity Maximization for Domain Adaptation [article]

Xiaofu Wu, Suofei hang, Quan Zhou, Zhen Yang, Chunming Zhao, Longin Jan Latecki
2020 arXiv   pre-print
Entropy minimization has been widely used in unsupervised domain adaptation (UDA). However, existing works reveal that entropy minimization only may result into collapsed trivial solutions.  ...  In order to achieve the possible minimum target risk for UDA, we show that diversity maximization should be elaborately balanced with entropy minimization, the degree of which can be finely controlled  ...  CONCLUSION Entropy minimization has been shown to be a powerful tool for domain adaptation.  ...
