Query: Tilde at WMT 2020: News Task Systems   This paper describes Tilde's submission to the WMT2020 shared task on news
translation for both directions of the English-Polish language pair in both the
constrained and the unconstrained tracks. We follow our submissions from the
previous years and build our baseline systems to be morphologically motivated
sub-word unit-based Transformer base models that we train using the Marian
machine translation toolkit. Additionally, we experiment with different
parallel and monolingual data selection schemes, as well as sampled
back-translation. Our final models are ensembles of Transformer base and
Transformer big models that feature right-to-left re-ranking.
