Non-Autoregressive Machine Translation: It's Not as Fast as it Seems

no code implementations4 May 2022 Jindřich Helcl, Barry Haddow, Alexandra Birch

In this paper, we point out flaws in the evaluation methodology present in the literature on NAR models and we provide a fair comparison between a state-of-the-art NAR model and the autoregressive submissions to the shared task.

Distributionally Robust Recurrent Decoders with Random Network Distillation

no code implementations RepL4NLP (ACL) 2022 Antonio Valerio Miceli-Barone, Alexandra Birch, Rico Sennrich

Neural machine learning models can successfully model language that is similar to their training distribution, but they are highly susceptible to degradation under distribution shift, which occurs in many practical applications when processing out-of-domain (OOD) text.

Cross-lingual Intermediate Fine-tuning improves Dialogue State Tracking

1 code implementation EMNLP 2021 Nikita Moghe, Mark Steedman, Alexandra Birch

In this work, we enhance the transfer learning process by intermediate fine-tuning of pretrained multilingual models, where the multilingual models are fine-tuned with different but related data and/or tasks.

Exploring Unsupervised Pretraining Objectives for Machine Translation

no code implementations Findings (ACL) 2021 Christos Baziotis, Ivan Titov, Alexandra Birch, Barry Haddow

Unsupervised cross-lingual pretraining has achieved strong results in neural machine translation (NMT), by drastically reducing the need for large parallel data.

Few-shot learning through contextual data augmentation

1 code implementation EACL 2021 Farid Arthaud, Rachel Bawden, Alexandra Birch

Machine translation (MT) models used in industries with constantly changing topics, such as translation or news agencies, need to adapt to new data to maintain their performance over time.

Bridging Linguistic Typology and Multilingual Machine Translation with Multi-View Language Representations

1 code implementation EMNLP 2020 Arturo Oncevay, Barry Haddow, Alexandra Birch

Sparse language vectors from linguistic typology databases and learned embeddings from tasks like multilingual machine translation have been investigated in isolation, without analysing how they could benefit from each other's language characterisation.

Towards Making the Most of Context in Neural Machine Translation

1 code implementation19 Feb 2020 Zaixiang Zheng, Xiang Yue, Shu-Jian Huang, Jia-Jun Chen, Alexandra Birch

Document-level machine translation manages to outperform sentence level models by a small margin, but have failed to be widely adopted.

A Latent Morphology Model for Open-Vocabulary Neural Machine Translation

1 code implementation ICLR 2020 Duygu Ataman, Wilker Aziz, Alexandra Birch

Translation into morphologically-rich languages challenges neural machine translation (NMT) models with extremely sparse vocabularies where atomic treatment of surface forms is unrealistic.

On the Importance of Word Boundaries in Character-level Neural Machine Translation

1 code implementation WS 2019 Duygu Ataman, Orhan Firat, Mattia A. Di Gangi, Marcello Federico, Alexandra Birch

Neural Machine Translation (NMT) models generally perform translation using a fixed-size lexical vocabulary, which is an important bottleneck on their generalization capability and overall translation quality.

Evaluating Discourse Phenomena in Neural Machine Translation

no code implementations NAACL 2018 Rachel Bawden, Rico Sennrich, Alexandra Birch, Barry Haddow

Despite gains using BLEU, multi-encoder models give limited improvement in the handling of discourse phenomena: 50% accuracy on our coreference test set and 53. 5% for coherence/cohesion (compared to a non-contextual baseline of 50%).

Predicting Target Language CCG Supertags Improves Neural Machine Translation

Our results on WMT data show that explicitly modeling target-syntax improves machine translation quality for German->English, a high-resource pair, and for Romanian->English, a low-resource pair and also several syntactic phenomena including prepositional phrase attachment.
