4 The baseline SMT needs to be reasonably good in the sense that the oracle BLEU score on the generated n-best introducing a new feature ℎ +1 and a new feature weight +1 .
the new feature is defined as the phrase-based SMt system, into which the CPtM is incorporated, is parameterized by ( , ), where is a vector of a handful of parameters used in the log-linear model of (1), with one weight for each feature; and is the projection matrices used in the CPtM defined by (2) and (3).
