Machine Translation with Unsupervised Length-Constraints
Table 7: Simplification
['Metric', 'DE-EN Base', 'DE-EN Simp.', 'DE+EN Base', 'DE+EN Simp.', 'All Base', 'All Simp']
Again, we are using the decoder embedding to represent the amount of BPE units in the sentences. We use a system for 1 language pair, 2 language pairs and the system using 8 language pairs. First, the system is able to reduce the number of BPE tokens in the text significantly. The amount of tokens is reduce by up to 48%. Since the number of tokens is nearly keep the same, this is also reflected in a better readability. On the other hand, we see that the translation quality is only affected slightly.
