Vicinal and categorical domain adaptation

چکیده
Unsupervised domain adaptation aims to learn a task classifier that performs well on the unlabeled target domain, by utilizing labeled source domain. Inspiring results have been acquired learning domain-invariant deep features via domain-adversarial training. However, its parallel design of and classifiers limits ability achieve finer category-level alignment. To promote categorical (CatDA), based joint category-domain classifier, we propose novel losses adversarial training at both category levels. Since can be regarded as concatenation individual respectively for two domains, our principle is enforce consistency predictions between classifiers. Moreover, concept vicinal domains whose instances are produced convex combination pairs from domains. Intuitively, alignment possibly infinite number enhances original We (VicDA) CatDA, leading Vicinal Categorical Domain Adaptation (ViCatDA). also Target Discriminative Structure Recovery (TDSR) recover intrinsic discrimination damaged feature analyze principles underlying key designs align distributions. Extensive experiments several benchmark datasets demonstrate new state art.

Sample-oriented Domain Adaptation for Image Classification
Image processing is a method to perform some operations on an image, in order to get an enhanced image or to extract some useful information from it. The conventional image processing algorithms cannot perform well in scenarios where the training images (source domain) that are used to learn the model have a different distribution with test images (target domain). Also, many real world applicat...
متن کاملLearning and Domain Adaptation
Domain adaptation is a fundamental learning problem where one wishes to use labeled data from one or several source domains to learn a hypothesis performing well on a different, yet related, domain for which no labeled data is available. This generalization across domains is a very significant challenge for many machine learning applications and arises in a variety of natural settings, includin...
متن کاملA Novel Image Denoising Method Based on Incoherent Dictionary Learning and Domain Adaptation Technique
In this paper, a new method for image denoising based on incoherent dictionary learning and domain transfer technique is proposed. The idea of using sparse representation concept is one of the most interesting areas for researchers. The goal of sparse coding is to approximately model the input data as a weighted linear combination of a small number of basis vectors. Two characteristics should b...
متن کاملFeature-Level Domain Adaptation
Domain adaptation is the supervised learning setting in which the training and test data are sampled from different distributions: training data is sampled from a source domain, whilst test data is sampled from a target domain. This paper proposes and studies an approach, called feature-level domain adaptation (flda), that models the dependence between the two domains by means of a feature-leve...
