Two experiments indicate that the proposed DIFE method could provide a better domain-invariant feature representation and successfully solve the cross-domain diagnosis problem under unseen working conditions.doi
Invariant feature representationOne of the serious challenges in computer vision and image classification is learning an accurate classifier for a new unlabeled image dataset, considering that there is no available labeled training data. Transfer learning and domain adaptation are two outstanding solutions ...
Domain-Invariant Feature Learning sourcet data和target data一起进网络训练,目标是让网络学到让source domain和target domain一致的domain- invariant feature representation,从而让source domain和target domain的分布没有差异。如图中的alignment component,方法包括:minimize divergence, perform reconstruction, employ adver...
这个误差界鼓励领域泛化的方法着力于domain invariant representation,即找到领域中不变的表征,减小上述误差界中的第一项,以及源域和目标域之间的表征分布差异,即减小表征空间上的\gamma和\rho。 Dataset The colored MNIST Dataset The original digits ranging from 0 to 4 were relabeled as 0 and the digits ran...
Next, PDD encourages the student models from different domains to gradually learn a domain-invariant feature representation towards the teacher, where the overlapping regions between agents are employed as guidance to facilitate the distillation process. Furthermore, DAF closes the domain gap between the...

This paper addresses the particularlyimportant and challenging domain-invariant representation learning task of unsupervised domainadaptation (Glorot et al., 2011; Li et al., 2014; Pan et al., 2011; Ganin et al., 2016). In unsuperviseddomain adaptation, the training data consists of labeled ...
By learning a feature representation that is both discriminative and invariant, these methods can effectively transfer knowledge from the source domain to the target domain. Model-based methods: These methods focus on modifying the model architecture to account for domain shift. For example, domain-...

我们首先使用style -swap[4]算法对原始源数据集的纹理进行多样性处理,然后使用CycleGAN[29]图像转换算法对原始源数据集进行转换。然后,我们的模型经过两个训练阶段。阶段1:我们训练一个分割模型与texturediversified数据集学习纹理不变表示。阶段2:基于纹理不变表示,我们根据目标域的纹理对模型进行微调。
