OVANet: One-vs-All Network for Universal Domain Adaptation [article]

Kuniaki Saito, Kate Saenko
2021 arXiv   pre-print
To learn the inter-and intra-class distance, we propose to train a one-vs-all classifier for each class using labeled source data.  ...  Universal Domain Adaptation (UNDA) aims to handle both domain-shift and category-shift between two datasets, where the main challenge is to transfer knowledge while rejecting unknown classes which are  ...  The idea of employing one-vs-all classifiers is effective for different networks. OVANet needs both open-set and closed-set classifiers.  ...

Towards Adaptive Unknown Authentication for Universal Domain Adaptation by Classifier Paradox [article]

Yunyun Wang, Yao Liu, Songcan Chen
2022 arXiv   pre-print
Universal domain adaptation (UniDA) is a general unsupervised domain adaptation setting, which addresses both domain and label shifts in adaptation.  ...  That is, a multi-class (MC) predictor classifies samples to one of the multiple source classes, while a binary one-vs-all (OVA) predictor further verifies the prediction by MC predictor.  ...  Universal Domain Adaptation As for UniDA, we perform UACP on Office-31, Office-Home, VisDA and DomainNet datasets.  ...

Exploiting Inter-Sample Affinity for Knowability-Aware Universal Domain Adaptation [article]

Yifan Wang and Lin Zhang and Ran Song and Lin Ma and Wei Zhang
2022 arXiv   pre-print
Universal domain adaptation (UDA) aims to transfer the knowledge of common classes from source domain to target domain without any prior knowledge on the label set, which requires to distinguish the unknown  ...  samples from the known ones in the target domain.  ...  The latest work OVANet [22] , proposed by Saito et al., trained a one-vs-all classifier for each class using labeled source samples and adapted the open-set classifier to the target domain.  ...

Gabriela Csurka, Riccardo Volpi, Boris Chidlovskii
2021 arXiv   pre-print
We present the most important semantic segmentation methods; we provide a comprehensive survey on domain adaptation techniques for semantic segmentation; we unveil newer trends such as multi-domain learning  ...  , domain generalization, test-time adaptation or source-free domain adaptation; we conclude this survey by describing datasets and benchmarks most widely used in semantic segmentation research.  ...  In European Conference on [158] Kuniaki Saito and Kate Saenko.
