## Projecte Aina’s Spanish-Aranese machine translation model
## Model description
This model was created as part of the participation of Language Technologies Unit at BSC in the WMT24 Shared Task:
[Translation into Low-Resource Languages of Spain](https://www2.statmt.org/wmt24/romance-task.html).
It results from a full fine-tuning of the NLLB-200-600M model with a Spanish-Aranese corpus.
Specifically, we used the [transformers library](https://huggingface.co/docs/transformers/) from Hugging Face and a filtered version
of the [Spanish-Aranese dataset](https://huggingface.co/datasets/projecte-aina/ES-OC_Parallel_Corpus) to fine-tune the model.
Since the original NLLB-200-600M doesn't support Aranese, we added a new token ("arn_Latn") to enable translation into Aranese.
This language tag helps the model recognize the source and target languages for translation.
The model was evaluated using the Flores+ evaluation datasets. Please refer to the [paper](__poner_link___) for more information.
## Intended uses and limitations
You can use this model for machine translation from Spanish to Aranese.
## Limitations and bias
At the time of submission, no measures have been taken to estimate the bias and toxicity embedded in the model.
However, we are well aware that our models may be biased. We intend to conduct research in these areas in the future, and if completed, this model card will be updated.
## Evaluation
### Variable and metrics
We use the BLEU and ChrF score for evaluation on the [Flores+](https://github.com/openlanguagedata/flores) evaluation datasets.
### Evaluation results
Below are the evaluation results on the machine translation from Spanish to Aranese compared to [Apertium](https://www.apertium.org/) and [Softcatala](https://www.softcatala.org/traductor/) (cascading through Catalan):
| Test set (BLEU) | Apertium | Softcatala | Our model |
|:---------------------|:---------|:-------|:-----------|
| Flores dev | 48.96 | 34.43 | **55.50** |
| Flores devtest | 28.85 | 26.07 | **30.12** |
| Test set (ChrF) | Apertium | Softcatala | Our model |
|:---------------------|:---------|:-------|:-----------|
| Flores dev | 72.63 | 58.61 | **76.04** |
| Flores devtest | 49.42 | 48.29 | **50.05** |
