| Challenge: | Mixture of Experts layers (MoEs) enable efficient scaling of language models . large autoregressive language models such as GPT-3 can be adapted to a wide range of tasks . |
| Approach: | They propose to use Mixture of Experts layers to enable efficient scaling of language models . they find that MoEs are substantially more compute efficient than dense models compared to MoE models - but only when they are more modestly trained . |
| Outcome: | The proposed model outperforms dense models in a wide range of tasks and domains. |

| Challenge: | Large-scale generative language models such as GPT-3 are competitive few-shot learners. |
| Approach: | They train multilingual generative language models on a corpus covering a diverse set of languages and study their few- and zero-shot learning capabilities. |
| Outcome: | The proposed model outperforms GPT-3 on 171 out of 182 directions with 32 training examples and surpasses the official supervised baseline in 45 directions. |

Copied to clipboard
| Challenge: | Existing methods to reduce interference in multilingual machine translation are often computationally intensive and do not always work. |
| Approach: | They propose to reduce interference in multilingual machine translation models by enlarging the model and tuning the sampling temperature to control the proportion of each language pair in the data. |
| Outcome: | The proposed model size, data size, and proportion of each language pair within the dataset determine interference (or synergy) . |
Multilingual Machine Translation with Hyper-Adapters (2022.emnlp-main)
Copied to clipboard
| Challenge: | Multilingual machine translation suffers from negative interference across languages. |
| Approach: | They propose a rescaling fix that reduces the number of parameters and enables training larger hyper-networks. |
| Outcome: | The proposed approach outperforms regular adapters and achieves the same performance with 12 times less parameters. |
Data Selection Curriculum for Neural Machine Translation (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Neural Machine Translation models are typically trained on heterogeneous data that are concatenated and randomly shuffled. |
| Approach: | They propose a two-stage curriculum training framework where a NMT model is fine-tuned on subsets of data, selected by deterministic scoring and online scoring. |
| Outcome: | The proposed framework improves on six language pairs comprising low- and high-resource languages and shows up to +2.2 BLEU improvement and faster convergence. |
Fixing MoE Over-Fitting on Low-Resource Languages in Multilingual Machine Translation (2023.findings-acl)
Copied to clipboard
| Challenge: | Sparsely gated Mixture of Experts (MoE) models are a compute-efficient method to scale model capacity for multilingual machine translation tasks. |
| Approach: | They propose a regularization strategy that prevents over-fitting of MoE models on low-resource tasks and conditional MoE Routing and curriculum learning methods that prevent over- fitting. |
| Outcome: | The proposed methods improve the performance of MoE models on low-resource tasks without adversely affecting high-res tasks. |
Revisiting Machine Translation for Cross-lingual Classification (2023.emnlp-main)
Copied to clipboard
| Challenge: | Recent work in cross-lingual learning has pivoted around multilingual models, which are typically pretrained on unlabeled corpora in multiple languages using some form of language modeling objective. |
| Approach: | They propose to use a stronger machine translation system to mitigat mismatch between training on original text and running inference on machine translated text. |
| Outcome: | The proposed approach is highly task dependent and calls into question the dominance of multilingual models for cross-lingual classification. |

| Challenge: | Large language models (LLMs) are rapidly deployed and continue to evolve through scaling. |
| Approach: | They propose a method to train strong long-context LLMs that are capable of utilizing massive context windows of up to 32,000 tokens. |
| Outcome: | The proposed model can surpass gpt-3.5-turbo-16k's overall performance on long-context benchmarks with a cost-effective instruction tuning procedure that is free of expensive annotations. |
Tricks for Training Sparse Translation Models (2022.naacl-main)
Copied to clipboard
| Challenge: | Multitask learning with an unbalanced data distribution skews model learning towards high resource tasks. |
| Approach: | They propose to use a temperature heating mechanism and dense pre-training to mitigate this by training models with a fixed model capacity. |
| Outcome: | The proposed techniques improve performance on two multilingual translation benchmarks compared to BASELayers and Dense scaling baselines and in combination, more than 2x model convergence speed. |
