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...
In this paper, a novel method, namely Wasserstein Distance Learned Feature Representations (WDLFR), is put forward for drift compensation, which is based on the domain invariant feature representation learning. It regards a neural network as a domain discriminator to measure the empirical Wass...
the fifirst framework to learn domain-invariant, contextual representation for UDA of time series data 介绍 Unsupervised domain adaptation (UDA) Domain adaptation 思想 :给定source dataset(源数据,也就是初始的训练集,有标签),target dataset(目标数据,就是相关域的数据集,无标签),Domain adaptation的目标就...
1.Domain adaptation aims at generalizing a high-performance learner on a target domain via utilizing the knowledge distilled from a source domain which has a different but related data distribution. One solution to domain adaptation is to learn domain invariant feature representations while the learned...
或者可以通过特征表示的方法(feature representation/transformation)的方式,将source domain和target domain的特征投影到第三个使得分布的偏差较小的domain当中。 基于实例(instance-based)的方法需要比较严格的假设:1)source domain和target domain的条件分布是相同的,2)source domain中的某些部分数据可以通过重新加权被重用...
The learning of domain-invariant representations in the context of domain adaptation with neural networks is considered. We propose a new regularization method that minimizes the discrepancy between domain-specific latent feature representations directly in the hidden activation space. Although some standard...

Due to the ability of deep neural nets to learn rich representations, recent advances in unsupervised domain adaptation have focused on learning domain-invariant features that achieve a small error on the source domain. The hope is that the learnt representation, together with the hypothesis learnt ...
