摘要:

Domain adaptation techniques refer to a class of methods that attempt to bridge the differences between the distributions of training and test data. This classical problem in pattern recognition and machine learning has generated renewed interest due to the multitudes of ways in which data is collected. First, we review recent methods developed for unsupervised domain adaptation using Grassmannian representations. Next, we present methods for unsupervised domain adaptation using sparse representations such as dictionaries. Finally, we present an approach that leverages unsupervised data to bring the source and target distributions closer in a learned joint feature space. This is accomplished by inducing a symbiotic relationship between the learned embedding and a generative adversarial network. We demonstrate the impact of these methods for object and face recognition as well as semantic segmentation problems.
