| Challenge: | state-of-the-art translation systems often fail in preserving meaning . ambiguity between source and target languages can cause translation problems . |
| Approach: | They propose to use a pre-trained neural sequence-to-sequence model to define a less ambiguous translation system. |
| Outcome: | The proposed system preserves meaning in two languages without compromising translation quality. |

Crossing the Threshold: Idiomatic Machine Translation through Retrieval Augmentation and Loss Weighting (2023.emnlp-main)
Copied to clipboard
| Challenge: | idioms are common in everyday language, but often pose a challenge to translators because their meanings do not follow from the meanings of their parts. |
| Approach: | They propose to use retrieval-augmented models to increase the accuracy of a strong pretrained machine translation model on idiomatic sentences by up to 13%. |
| Outcome: | The proposed techniques improve the accuracy of a strong pretrained model on idiomatic sentences by up to 13% in absolute accuracy, and holds potential benefits for non-idiomatic phrases. |
Lost in Back-Translation: Emotion Preservation in Neural Machine Translation (2020.coling-main)
Copied to clipboard
| Challenge: | MT is used to support human-to-human communication across languages, but it is unclear whether it can translate the non-propositional level of emotions. |
| Approach: | They propose to use a re-ranking approach to change emotions to reverse this tendency . they find that emotions are toned down or amplified through linguistic changes . |
| Outcome: | The proposed model can be used to change emotions, and it can be applied to other languages. |

Improving Lexical Choice in Neural Machine Translation (N18-1)

| Challenge: | False positives: the output layer rewards frequent words disproportionately, we argue . Falsibles: a model that learns word representations in continuous space tends to translate rare words . |
| Approach: | They propose to fix the norms of both vectors to a constant value and integrate a lexical module which is jointly trained with the rest of the model. |
| Outcome: | The proposed approach achieves improvements of up to +4.3 BLEU surpassing phrase-based translation in nearly all settings. |
Tagged Back-translation Revisited: Why Does It Really Work? (2020.acl-main)
Copied to clipboard
| Challenge: | In this paper, we show that neural machine translation systems trained on large back-translated data overfit some of the characteristics of machine-transcribed texts. |
| Approach: | They propose to add a tag to back-translations to help distinguish back-translated data from original parallel training data. |
| Outcome: | The proposed tag helps the system distinguish back-translated data from original parallel training data and is as effective as a tag in high-resource training. |
