Query: Dynamic Distillation Network for Cross-Domain Few-Shot Recognition with
  Unlabeled Data   Most existing works in few-shot learning rely on meta-learning the network on
a large base dataset which is typically from the same domain as the target
dataset. We tackle the problem of cross-domain few-shot learning where there is
a large shift between the base and target domain. The problem of cross-domain
few-shot recognition with unlabeled target data is largely unaddressed in the
literature. STARTUP was the first method that tackles this problem using
self-training. However, it uses a fixed teacher pretrained on a labeled base
dataset to create soft labels for the unlabeled target samples. As the base
dataset and unlabeled dataset are from different domains, projecting the target
images in the class-domain of the base dataset with a fixed pretrained model
might be sub-optimal. We propose a simple dynamic distillation-based approach
to facilitate unlabeled images from the novel/base dataset. We impose
consistency regularization by calculating predictions from the weakly-augmented
versions of the unlabeled images from a teacher network and matching it with
the strongly augmented versions of the same images from a student network. The
parameters of the teacher network are updated as exponential moving average of
the parameters of the student network. We show that the proposed network learns
representation that can be easily adapted to the target domain even though it
has not been trained with target-specific classes during the pretraining phase.
Our model outperforms the current state-of-the art method by 4.4% for 1-shot
and 3.6% for 5-shot classification in the BSCD-FSL benchmark, and also shows
competitive performance on traditional in-domain few-shot learning task.
