Περίληψη

Domain Adaptation (DA) aims to close the gap in classification performance between the source domain used for training and the target domain where testing takes place. Such performance loss is often encountered due to the dataset bias attributed to changes in the data distributions between the source and target. This seminar begins with a taxonomy of domain adaptation methods, e.g. closed set, open set, unsupervised or semi-supervised. We then present an overview of DA techniques utilizing manifold learning and deep learning, including our methods on manifold-aligned domain adaptation and targeted adversarial domain adaptation. Finally, we address a new DA scenario where the target domain samples are not available all at once, but are acquired in small batches over time and adaptation takes place continually. Our Continual Domain Adaptation methods unitilize concepts from both DA and continual learning. Experiments on various datasets demonstrate the benefits of Continual Domain Adaptation under challenging, data-constrained conditions.
