# nllb-200-distilled-600M-OpenSLR-GL-EN |
|
|
|
This model is a fine-tuned version of [facebook/nllb-200-distilled-600M](https://huggingface.co/facebook/nllb-200-distilled-600M) on [juanjucm/GoogleOSHQ-SpeechT-GL-EN](https://huggingface.co/datasets/juanjucm/GoogleOSHQ-SpeechT-GL-EN) datasetfor **Galician-to-Englis Machine Translation** task. It takes Galician texts as input and generates the correspondant English translation. |
|
|
|
This Machine Translation model, was developed to be the second stage of a Speech Translation cascade system for transcribing and translating Galician audios into English texts. [This STT model](https://huggingface.co/juanjucm/whisper-large-v3-turbo-FLEURS-GL) can be used as a first step to transcribe Galician audio into text. After that, this MT model can be applied over the generated Galician transcriptions to get English text translations. |
|
|
|
The motivation behind this work is to increase the visibility of the Galician language, making it more accessible for non-Galician speakers to understand and engage with Galician audio content. |
|
|
|
This model was developed during a 3-week Speech Translation workshop organised by [Yasmin Moslem](https://huggingface.co/ymoslem). |
|
|
|
### Performance and training details |
|
|
|
Baseline model achieved a BLEU score of **51.32** on the evaluation dataset. |
|
|
|
After fine-tuning, it achieves the following results on the evaluation set: |
|
- Loss: 0.0122 |
|
- **BLEU: 73.6259** |
|
|
|
The following hyperparameters were used during training: |
|
- learning_rate: 1e-05 |
|
- train_batch_size: 4 |
|
- eval_batch_size: 4 |
|
- seed: 42 |
|
- gradient_accumulation_steps: 2 |
|
- total_train_batch_size: 8 |
|
- optimizer: Use adamw_torch with betas=(0.9,0.999) and epsilon=1e-08 and optimizer_args=No additional optimizer arguments |
|
- lr_scheduler_type: linear |
|
- num_epochs: 8 |
|
|
|
### Training results |
|
|
|
We used [BLEU Score](https://en.wikipedia.org/wiki/BLEU) as our reference translation metric for selecting the best checkpoint after training. |
