Supplementary material for: The balancing principle for parameter choice in distance-regularized domain adaptation

The main criterion used to define the balancing principle is as follows. Using the instantiation bound of the balancing principle in Eq. (1) further implies that null ε Figure 1 provides a helpful illustration for the last two steps. Our main theorem is stated as follows. Eq. (1) and the same monotonicity argument as used in the proof of Lemma 1, see also Figure 1. The average count of images of DomainNet in each class, and across all domains is approx.
