Considering the fact that Self-Adapt is performing pseudo-labelling, similar to other self-training methods, it is interesting to see how well it compares against classical selftraining methods for inducing labels (Yarowsky, 1995;Abney, 2007;Zhou and Li, 2005;Søgaard, 2010) when applied to UDA.
we consider the classical self-training (Yarowsky, 1995;Abney, 2007) (Self), Tri-training (Zhou and Li, 2005) (Tri) and Tri-training with diversification (Søgaard, 2010) (Tri-D).
