If we were interested in optimizing performance for each language separately (i.e., by using the development set on which we are reporting results as a tuning set), then we would be done now.
this grammar is an implementation of grammar (3) (AG Compounding) from (Sirts and Goldwater, 2013) without the compounding (since the compounding did not perform well for our languages), and we list it among our baselines in the result table.
