Gradual Source Domain Expansion for Unsupervised Domain Adaptation

1 code implementation16 Nov 2023 Thomas Westfechtel, Hao-Wei Yeh, Dexuan Zhang, Tatsuya Harada

Unsupervised domain adaptation (UDA) tries to overcome the need for a large labeled dataset by transferring knowledge from a source dataset, with lots of labeled data, to a target dataset, that has no labeled data.

Unsupervised Domain Adaptation via Minimized Joint Error

no code implementations1 Jan 2021 Dexuan Zhang, Tatsuya Harada

In this paper, we argue that the joint error is essential for the domain adaptation problem, in particular if the samples from different classes in source/target are closely aligned when matching the marginal distributions.

no code implementations3 Oct 2019 Dexuan Zhang, Tatsuya Harada

In this work, we present a novel upper bound of target error to address the problem for unsupervised domain adaptation.
