- Abstract summary: Unsupervised domain adaptation facilitates the unlabeled target domain relying on well-established source domain information.
Conventional methods forcefully reducing the domain discrepancy in the latent space will result in the destruction of intrinsic data structure.
We propose a Bi-Directional Generation domain adaptation model with consistent classifiers interpolating two intermediate domains to bridge source and target domains.

- Abstract: Unsupervised domain adaptation facilitates the unlabeled target domain
relying on well-established source domain information. The conventional methods
forcefully reducing the domain discrepancy in the latent space will result in
the destruction of intrinsic data structure. To balance the mitigation of
domain gap and the preservation of the inherent structure, we propose a
Bi-Directional Generation domain adaptation model with consistent classifiers
interpolating two intermediate domains to bridge source and target domains.
Specifically, two cross-domain generators are employed to synthesize one domain
conditioned on the other. The performance of our proposed method can be further
enhanced by the consistent classifiers and the cross-domain alignment
constraints. We also design two classifiers which are jointly optimized to
maximize the consistency on target sample prediction. Extensive experiments
verify that our proposed model outperforms the state-of-the-art on standard
cross domain visual benchmarks.

Unsupervised Domain Adaptation [31.150256154504696]
Unsupervised Domain Adaptation (UDA) has propelled the deployment of deep learning from limited experimental datasets into real-world unconstrained domains.
Most UDA approaches align features within a common embedding space and apply a shared classifier for target prediction.
We propose to simultaneously conduct feature alignment in two individual spaces focusing on different domains, and create for each space a domain-oriented classifier.

Face anti-spoofing approaches based on unsupervised domain adaption (UDA) have drawn growing attention due to promising performances for target scenarios.
Most existing UDA FAS methods typically fit the trained models to the target domain via aligning the distribution of semantic high-level features.
We propose a novel perspective of UDA FAS that directly fits the target data to the models, stylizes the target data to the source-domain style via image translation, and further feeds the stylized data into the well-trained source model for classification.

Segmentation [74.3349233035632]
Existing techniques to adapt semantic segmentation networks across the source and target domains within deep convolutional neural networks (CNNs) do not consider an inter-class variation within the target domain itself or estimated category.
We introduce a learnable clustering module, and a novel domain adaptation framework called cross-domain grouping and alignment.
Our method consistently boosts the adaptation performance in semantic segmentation, outperforming the state-of-the-arts on various domain adaptation settings.
