[Review] Domain-Adversarial Training of Neural Network Link : [1505.07818] Domain-Adversarial Training of Neural Networks (arxiv.org) Domain-Adversarial Training of Neural Networks We introduce a new representation learning approach for domain adaptation, in which data at training and test time come from similar but different distributions. Our approach is directly inspired by the theory on domain adaptation suggesting that, for effe arxiv.org Summa..
