Query: The Enforced Transfer: A Novel Domain Adaptation Algorithm   Existing Domain Adaptation (DA) algorithms train target models and then use
the target models to classify all samples in the target dataset. While this
approach attempts to address the problem that the source and the target data
are from different distributions, it fails to recognize the possibility that,
within the target domain, some samples are closer to the distribution of the
source domain than the distribution of the target domain. In this paper, we
develop a novel DA algorithm, the Enforced Transfer, that deals with this
situation. A straightforward but effective idea to deal with this dilemma is to
use an out-of-distribution detection algorithm to decide if, during the testing
phase, a given sample is closer to the distribution of the source domain, the
target domain, or neither. In the first case, this sample is given to a machine
learning classifier trained on source samples. In the second case, this sample
is given to a machine learning classifier trained on target samples. In the
third case, this sample is discarded as neither an ML model trained on source
nor an ML model trained on target is suitable to classify it. It is widely
known that the first few layers in a neural network extract low-level features,
so the aforementioned approach can be extended from classifying samples in
three different scenarios to classifying the samples' activations after an
empirically determined layer in three different scenarios. The Enforced
Transfer implements the idea. On three types of DA tasks, we outperform the
state-of-the-art algorithms that we compare against.
