Press media, one form of mass media, manifests itself in large, diachronic collections of newspaper articles; such corpora provide a promising avenue for studying public opinion and testing theories, provided scholars can be confident that the measures they obtain over time are substantively invariant (Davidov et al., 2014).
the core intuition behind consistency regularization is that ensembled predictions are more likely to be correct than single predictions (Laine and Aila, 2017;tarvainen and Valpola, 2017).
