Domain Invariant and Class Discriminative Heterogeneous Domain Adaptation

Heterogeneous domain adaptation (HDA) aims to improve the task of target domain by source domain, despite the data distribution of source and target domains are different. In our algorithm, we match the marginal and condition distribution, and introduce the repulsive force term to expand the difference between classes. Finally we find a latent subspace by learning different transformations for different domains. At the same time, we add structural consistency constraints and ℓ
