Learning to Adapt: Digging Deeper into Domain Adaptation for Visual Recognition in Real-world and Dynamic Environments
Deep networks have significantly improved the state of the arts for several tasks in computer vision. Unfortunately, the impressive performance gains have come at the price of a use of massive amounts of labeled data. As the cost of collecting and annotating data is often prohibitive, given a target task where few or no training samples are available, it would be desirable to build effective learners that can leverage information from labeled data of a different but related source domain. However, a major obstacle in adapting models to the target task is the shift in data distributions across domains. This problem, typically referred as domain shift, has motivated research into Domain Adaptation (DA). Traditional DA algorithms assume the presence of a single source and a single target domain. However, in real-world applications different situations may arise. For instance, in some cases multiple datasets from diverse source domains may be available, while in other settings target samples may not be given at the training stage or may arise from temporal data streams. Alternatively, in some applications knowledge about different domains may only be provided in form of side-information (e.g. metadata, captions) and should be effectively exploited to guide the adaptation process. In this talk I will provide an overview of the problem of DA, focusing onvisual recognition tasks, and describe recent works on adaptation in case of dynamic, real-world settings.
