We use a maximum ... Arabic-English translation task. 1 Introduction In this paper, we present a block -based model for statis- tical machine translation. A block is a pair of phrases which are translations of each other. For ... 4 Online Training of Maximum- entropy Model The local model described in Section 3 leads to the fol- lowing abstract maximum entropy training formulation: (8) In this formulation, is the weight...
