无监督域自适应在解决训练集(源域)和测试集(目标域)分布不一致的问题上已经取得了一定的成功.在面向低能耗场景和开放动态任务环境时,在资源约束和开放类别出现的情况下,现有的无监督域自适应方法面临着严峻的挑战.源域无关开集域自适应(SF-ODA)旨在将源域模型中的知识迁移到开放类出现的无标签目标域,从而在无源域数据资源的限制下辨别公共类和检测开放类.现有的源域无关开集域自适应的方法聚焦于设计准确检测开放类别的源域模型或增改模型的结构.但是,这些方法不仅需要额外的存储空间和训练开销,而且在严格的隐私保护场景下难以实现.提出了一个更加实际的场景:主动学习的源域无关开集域自适应(ASF-ODA),目标是基于一个普通训练的源域模型和少量专家标注的有价值的目标域样本来实现鲁棒的迁移.为了达成此目标,提出了局部一致性主动学习(LCAL)算法.首先,利用目标域中局部特征标签一致的特点,LCAL设计了一种新的主动选择方法:局部多样性选择,来挑选更有价值的阈值模糊样本来促进开放类和公共类分离.接着,LCAL基于信息熵初步筛选出潜在的公共类集合和开放类集合,并利用第一步得到的主动标注样本对这两个集合进行匹配纠正,得到两个对应的可信集合.最后,LCAL引入开集损失和信息最大化损失来进一步促使公共类和开放类分离,引入交叉熵损失来实现公共类的辨别.在Office-31、Office-Home和VisDA-C这3个公开的基准数据集上的大量实验表明:在少量有价值的目标域样本的帮助下,LCAL不仅显著优于现有的源域无关开集域自适应方法,还大幅度超过了现有的主动学习方法的表现,在某些迁移任务上可以提升20%.
