摘要:

部分自适应(PDA)解决了目标域只包含源域中类的子集的实际情况。虽然PDA应该同时考虑班级水平和样本水平来减轻负迁移,但目前的方法大多只依赖其中之一。在本文中,我们提出了一种新的方法来充分利用多层次的关联,可以出现在PDA。我们的关联部分领域自适应(APDA)利用域内关联,主动选择出非平凡的异常样本,在每个源私有类的样本级加权不能处理。此外,我们的方法考虑域间关联,以鼓励积极的转移附近的目标样本和源样本之间的映射具有高标签共性。为此,我们利用特征传播在一个建议的标签空间组成的源地面实况标签和目标概率标签。我们进一步提出了一个几何指导损失的基础上,每个源类的标签共性,以鼓励积极的转移。我们的APDA在公共数据集上始终实现最先进的性能。

英文摘要:

Partial Adaptation (PDA) addresses a practical scenario in which the target domain contains only a subset of classes in the source domain. While PDA should take into account both class-level and sample-level to mitigate negative transfer, current approaches mostly rely on only one of them. In this paper, we propose a novel approach to fully exploit multi-level associations that can arise in PDA. Our Associative Partial Domain Adaptation (APDA) utilizes intra-domain association to actively select out non-trivial anomaly samples in each source-private class that sample-level weighting cannot handle. Additionally, our method considers inter-domain association to encourage positive transfer by mapping between nearby target samples and source samples with high label-commonness. For this, we exploit feature propagation in a proposed label space consisting of source ground-truth labels and target probabilistic labels. We further propose a geometric guidance loss based on the label commonness of each source class to encourage positive transfer. Our APDA consistently achieves state-of-the-art performance across public datasets.
