<!-- Provide a quick summary of what the model is/does. --> |
|
|
|
Lugha-Llama is an Africa-centric language model developed through continual pretraining with [WURA dataset](https://huggingface.co/datasets/castorini/wura), a large African languages corpora which consists of sixteen low-resource African languages and four high-resource |
|
languages commonly spoken on the African continent. |
|
|
|
To train the model, we sample as uniformly as possible across languages while limiting the number of times data is repeated and upsample rare languages by at most four epochs. |
|
We combine [WURA data](https://huggingface.co/datasets/castorini/wura) with high-quality English documents from [FineWeb-Edu](https://huggingface.co/spaces/HuggingFaceFW/blogpost-fineweb-v1) and [OpenWebMath](https://huggingface.co/datasets/open-web-math/open-web-math) which results into improved Lugha-Llama-Edu and Lugha-Llama-Maths models respectively. |
|
Our models consistently achieve the best performance amongst similary-sized baselines. |
|
|
|
In a separate ablation experiment, we translate English education documents to Swahili to study whether the performance gains from FineWeb-Edu data is due to its content or English source language. [FineWeb_Edu-swahili-translated](https://huggingface.co/datasets/princeton-nlp/fineweb_edu-swahili-translated). |

We demonstrate the findings in our paper [Adapting Large Language Models for African Languages: |
|
The Lugha-Llama Model]() |
