[PDF] Top 20 Efficient Left to Right Hierarchical Phrase Based Translation with Improved Reordering

... To evaluate the performance of LR-Hiero decod- ing with cube pruning (LR-Hiero+CP), we compare it with three baselines: (i) CKY Hiero, (ii) CKY Hiero-GNF, and (iii) LR-Hiero (without cube prun- ing) with two different ... See full document
