Multilingual Arbitration: Optimizing Data Pools to Accelerate Multilingual Progress (2025.acl-long)
Copied to clipboard
| Challenge: | Synthetic data generation relies on a single oracle teacher model, which can lead to model collapse and bias propagation. |
| Approach: | They propose a multilingual arbitration approach that exploits performance variations among multiple models for each language. |
| Outcome: | The proposed approach surpasses single-teacher distillation with 80% win rates over proprietary and open-weight models with the largest improvements in low-resource languages. |

| Challenge: | (2020) African languages are underrepresented in existing natural language processing datasets, research, and tools due to lack of datasets and reproducible results. |
| Approach: | They propose to create a dataset for named entity recognition (NER) in ten African languages. |
| Outcome: | The results of the first large dataset for named entity recognition (NER) in ten African languages are released to inform future research on African NLP. |

| Challenge: | Existing datasets in the English language are mostly in the realm of instruction fine-tuning . aya dataset, the Aya Collection, and the AYa Evaluation Suite are key resources . |
| Approach: | They aim to build a human-curated instruction-following dataset spanning 65 languages . they work with fluent speakers of languages from around the world to collect natural instances of instructions and completions . |
| Outcome: | The goal is to build a human-curated instruction-following dataset spanning 65 languages. |
When Life Gives You Samples: The Benefits of Scaling up Inference Compute for Multilingual LLMs (2025.emnlp-main)
Copied to clipboard
| Challenge: | Recent advances in large language models have shifted focus toward scaling inference-time compute. |
| Approach: | They propose to scale inference-time compute in a multilingual, multi-task setting . they propose to use m-ArenaHard-v2.0 prompts to sample multiple outputs in parallel . |
| Outcome: | The proposed solutions achieve an average +6.8 jump in win-rates for 8B models on m-ArenaHard-v2.0 prompts in non-English languages against proprietary models like Gemini. |
