When Does Monolingual Data Help Multilingual Translation: The Role of Domain and Model Scale

no code implementations23 May 2023 Christos Baziotis, Biao Zhang, Alexandra Birch, Barry Haddow

Next, we analyze the impact of scale (from 90M to 1. 6B parameters) and find it is important for both methods, particularly DAE.

Multilingual Machine Translation with Hyper-Adapters

3 code implementations22 May 2022 Christos Baziotis, Mikel Artetxe, James Cross, Shruti Bhosale

We find that hyper-adapters are more parameter efficient than regular adapters, reaching the same performance with up to 12 times less parameters.

Attention-based Conditioning Methods for External Knowledge Integration

1 code implementation ACL 2019 Katerina Margatina, Christos Baziotis, Alexandros Potamianos

This form of conditioning on the attention distribution, enforces the contribution of the most salient words for the task at hand.

SEQ^3: Differentiable Sequence-to-Sequence-to-Sequence Autoencoder for Unsupervised Abstractive Sentence Compression

1 code implementation7 Apr 2019 Christos Baziotis, Ion Androutsopoulos, Ioannis Konstas, Alexandros Potamianos

The proposed model does not require parallel text-summary pairs, achieving promising results in unsupervised sentence compression on benchmark datasets.
