Learning variable length units for SMT between related languages via Byte Pair Encoding
Table 6: Translation accuracies for Joint BPE models trained with different number of merge operations (BLEU). The Bestprev indicates the best performing units and their accuracy scores from Tables 3 and 4 shown for comparison.
['[EMPTY]', '[BOLD] Best [ITALIC] prev', '[BOLD] JB1 [ITALIC] k', '[BOLD] JB2 [ITALIC] k', '[BOLD] JB3 [ITALIC] k', '[BOLD] JB4 [ITALIC] k']
We do not see any major improvement over the monolingual BPE model due to the joint BPE model.
