Online Learning for Effort Reduction in Interactive Neural Machine Translation
Table 13: Results of translation quality for all tasks in terms of TER [%] and BLEU [%] comparing regular LSTM units and cLSTM units. cLSTM figures are the same than in Table 2. Results that are statistically significantly better for each task and metric are boldfaced.
['[EMPTY]', '[EMPTY]', 'TER [%] LSTM', 'TER [%] cLSTM', 'BLEU [%] LSTM', 'BLEU [%] cLSTM']
In all cases, the systems featuring cLSTM units performed better than those with classical LSTM. The differences were consistent and constant across all tasks: cLSTM units increased the BLEU from around 2 to 3 points. TER was also improved in all cases, in this case from around 2 to almost 5 points.
