摘要:

典型的领域自适应方法是对在源域(例如,晴天)以实现对目标域中的测试数据的高性能(例如,雨天)。无论目标包含单个同质域还是多个异质域,现有的工作总是假设域之间存在明显的区别,这在实践中往往是不正确的(例如,天气变化)。我们研究了一个开放的复合领域自适应(OCDA)问题,其中的目标是一个复合的多个同质域没有域标签,反映现实的数据汇集从混合和新的情况。我们提出了一种新的方法,基于两个技术见解OCDA:1)课程领域自适应策略,以数据驱动的自组织方式引导跨领域的泛化和2)内存模块,以增加模型的敏捷性对新的领域。我们在数字分类、表情识别、语义分割和强化学习上的实验证明了该方法的有效性。

英文摘要:

A typical domain adaptation approach is to adapt models trained on the annotated data in a source domain (e.g., sunny weather) for achieving high performance on the test data in a target domain (e.g., rainy weather). Whether the target contains a single homogeneous domain or multiple heterogeneous domains, existing works always assume that there exist clear distinctions between the domains, which is often not true in practice (e.g., changes in weather). We study an open compound domain adaptation (OCDA) problem, in which the target is a compound of multiple homogeneous domains without domain labels, reflecting realistic data collection from mixed and novel situations. We propose a new approach based on two technical insights into OCDA: 1) a curriculum domain adaptation strategy to bootstrap generalization across domains in a data-driven self-organizing fashion and 2) a memory module to increase the model's agility towards novel domains. Our experiments on digit classification, facial expression recognition, semantic segmentation, and reinforcement learning demonstrate the effectiveness of our approach.
