摘要:

部分领域自适应旨在将知识从一个更大、更多样化的源领域适应到一个更小、类数更少的目标领域,引起了人们的广泛关注。最近的实践领域自适应管理提取有效的功能,通过合并的伪标签的目标域,以更好地对抗跨域分布的分歧。但是,必须将目标数据与一小部分源数据对齐。在本文中,我们开发了一种新的判别式跨域特征学习(DCDF)框架,以迭代优化目标标签与跨域图的加权方案。具体地说,提出了一种加权跨域中心损失和加权跨域图传播耦合未标记的目标数据到相关的源样本的歧视性跨域特征学习,其中无关的源中心将被忽略,以减轻边缘和条件的差异同时。通过与现有的部分领域自适应方法进行比较,在几个常用的标准测试集上的实验结果表明了该方法在促进未标记目标域识别方面的有效性.

英文摘要:

Partial domain adaptation aims to adapt knowledge from a larger and more diverse source domain to a smaller target domain with less number of classes, which has attracted appealing attention. Recent practice on domain adaptation manages to extract effective features by incorporating the pseudo labels for the target domain to better fight off the cross-domain distribution divergences. However, it is essential to align target data with only a small set of source data. In this paper, we develop a novel Discriminative Cross-Domain Feature Learning (DCDF) framework to iteratively optimize target labels with a cross-domain graph in a weighted scheme. Specifically, a weighted cross-domain center loss and weighted cross-domain graph propagation are proposed to couple unlabeled target data to related source samples for discriminative cross-domain feature learning, where irrelevant source centers will be ignored, to alleviate the marginal and conditional disparities simultaneously. Experimental evaluations on several popular benchmarks demonstrate the effectiveness of our proposed approach on facilitating the recognition for the unlabeled target domain, through comparing it to the state-of-the-art partial domain adaptation approaches.
