- Abstract: Domain Adaptation is the process of alleviating distribution gaps between
data from different domains. In this paper, we show that Domain Adaptation
methods using pair-wise relationships between source and target domain data can
be formulated as a Graph Embedding in which the domain labels are incorporated
into the structure of the intrinsic and penalty graphs. Specifically, we
analyse the loss functions of three existing state-of-the-art Supervised Domain
Adaptation methods and demonstrate that they perform Graph Embedding. Moreover,
we highlight some generalisation and reproducibility issues related to the
experimental setup commonly used to demonstrate the few-shot learning
capabilities of these methods. To assess and compare Supervised Domain
Adaptation methods accurately, we propose a rectified evaluation protocol, and
report updated benchmarks on the standard datasets Office31 (Amazon, DSLR, and
Webcam), Digits (MNIST, USPS, SVHN, and MNIST-M) and VisDA (Synthetic, Real).

for Adaptive Object Detection [86.98573522894961]
We propose a framework that generalizes the components commonly used by Unsupervised Domain Adaptation (UDA) algorithms for detection.
Specifically, we propose a novel UDA algorithm, ViSGA, that leverages the best design choices and introduces a simple but effective method to aggregate features at instance-level.
We show that both similarity-based grouping and adversarial training allows our model to focus on coarsely aligning feature groups, without being forced to match all instances across loosely aligned domains.
