Our next experiment teases those two aspects apart and clearly shows the effect of the objective function.
we compare the traditionally used conditional log-likelihood (CLL) objective to expected BLEU on the French-English translation task in a small feature condition (SparseHRM) Table 4: French-English results on the SparseHRMLocal feature set when when trained with pair-wise ranked optimization (PRO) and expected BLEU (xBLEU).
