Figure 3 Generalization

[Yussef93]

Hi,Interesting work! I'd like to inquire about the relation of Figure 3 w.r.t TTA. Generalisation differs a lot than TTA what message do you try to deliver with tuning on domain i and evaluating on j this seems as domain generalisation not TTA as TTA should evaluate on the same test sample from the same domain after adaptation. Clarification would be appreciated!
