To overcome above problems, we only employ the bilingual phrase pairs in the dynamic cache to inform the decoder whether one bilingual phrase pair exists in the dynamic cache or not, which is slightly similar to (Nepveu et al, 2004) ,thus avoiding extra computational burden and the fine-tuning of the decay factor.
following new feature is incorporated to better explore the dynamic cache: ∨ e =e ∧f =f ∧∥ e ∥>3 ∨ e =e ∧f =f ∧∥ e ∥>3 0 other Here, F is called the dynamic cache feature.
