Recent advances in deep domain adaptation reveal that adversarial learning
can be embedded into deep networks to learn transferable features that reduce
distribution discrepancy between the source and target domains. Existing domain
adversarial adaptation methods based on single domain discriminator only align
the source and target data distributions without exploiting the complex
multimode structures. In this paper, we present a multi-adversarial domain
adaptation (MADA) approach, which captures multimode structures to enable
fine-grained alignment of different data distributions based on multiple domain
discriminators. The adaptation can be achieved by stochastic gradient descent
with the gradients computed by back-propagation in linear-time. Empirical
evidence demonstrates that the proposed model outperforms state of the art
methods on standard domain adaptation datasets.
