Simple Domain Adaptation with Class Prediction Uncertainty Alignment
share
Unsupervised domain adaptation tries to adapt a classifier trained on a labeled source domain to a related but unlabeled target domain. Methods based on adversarial learning try to learn a representation that is at the same time discriminative for the labels yet incapable of discriminating the domains. We propose a very simple and efficient method based on this approach which only aligns predicted class probabilities across domains. Experiments show that this strikingly simple adversarial domain adaptation method is robust to overfitting and achieves state-of-the-art results on datasets for image classification.
