+# mt-dspec-health-en-cy
+A language translation model for translating between English and Welsh, specialised to the specific domain of Health and care.
+
+This model was trained using custom DVC pipeline employing [Marian NMT](https://marian-nmt.github.io/), 
+the datasets prepared were generated from the following sources:
+ - [UK Government Legislation data](https://www.legislation.gov.uk)
+ - [OPUS-cy-en](https://opus.nlpl.eu/)
+ - [Cofnod Y Cynulliad](https://record.assembly.wales/)
+ - [Cofion Techiaith Cymru](https://cofion.techiaith.cymru)
+
+The data was split into train, validation and tests sets, the test set containing health-specific segments from TMX files
+selected at random from the [Cofion Techiaith Cymru](https://cofion.techiaith.cymru) website, which have been pre-classified as pertaining to the specific domain.
+Having extracted the test set, the aggregation of remaining data was then split into 10 training and validation sets, and fed into 10 marian training sessions.
+
+A website demonstrating use of this model is available at http://cyfieithu.techiaith.cymru.
+
+## Evaluation
+
+Evaluation was done using the python libraries [SacreBLEU](https://github.com/mjpost/sacrebleu) and [torchmetrics](https://torchmetrics.readthedocs.io/en/stable/).
+
+## Usage
+
+Ensure you have the prerequisite python libraries installed:
+
+```bash
+pip install transformers sentencepiece
+```
+
+```python
+import trnasformers
+model_id = "techiaith/mt-spec-health-en-cy"
+tokenizer = transformers.AutoTokenizer.from_pretrained(model_id)
+model = transformers.AutoModelForSeq2SeqLM.from_pretrained(model_id)
+translate = transformers.pipeline("translation", model=model, tokenizer=tokenizer)
+translated = translate("The doctor will be late to attend to patients this morning.")
+print(translated["translation_text"])
+```
