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.

本研究提出了双向生成领域自适应模型，通过一致分类器插值两个中间域来平衡减轻域差异和保留内在结构，使用跨领域对齐约束来进一步增强性能，设计了两个分类器，联合优化以最大化目标样本预测的一致性。广泛的实验证明，我们提出的模型在标准跨域视觉基准上优于现有技术。
