Abstract

Aiming at the problem of inconsistent probability distribution between training samples and test samples in machine learning, this paper proposed a semi-supervised domain adaptation method based on dropout regularization to transfer neural representations from label-rich source domains to unlabeled target domains. From the perspective of semi-supervised learning, this paper added a small amount of labeled target domain data into the source domain data, so that the neural network could learn the feature distribution of target domain data while learning the feature distribution of source domain data. With the gui-dance of prior knowledge, neural network could fit target domain data well even without abundant label information. Experiments show that the proposed algorithm is superior to other existing algorithms in domain adaptation performance on digital datasets and robust on real datasets covering a wide range of natural categories.
