Query: Discriminative Adversarial Domain Adaptation   Given labeled instances on a source domain and unlabeled ones on a target
domain, unsupervised domain adaptation aims to learn a task classifier that can
well classify target instances. Recent advances rely on domain-adversarial
training of deep networks to learn domain-invariant features. However, due to
an issue of mode collapse induced by the separate design of task and domain
classifiers, these methods are limited in aligning the joint distributions of
feature and category across domains. To overcome it, we propose a novel
adversarial learning method termed Discriminative Adversarial Domain Adaptation
(DADA). Based on an integrated category and domain classifier, DADA has a novel
adversarial objective that encourages a mutually inhibitory relation between
category and domain predictions for any input instance. We show that under
practical conditions, it defines a minimax game that can promote the joint
distribution alignment. Except for the traditional closed set domain
adaptation, we also extend DADA for extremely challenging problem settings of
partial and open set domain adaptation. Experiments show the efficacy of our
proposed methods and we achieve the new state of the art for all the three
settings on benchmark datasets.
