# Esperanto -> Catalan, English, Spanish MT Model
## Model description
This repository contains a **multilingual MarianMT** model for **Esperanto → (English, Spanish, Catalan)** translation using language tags with tiny architecture.
This model is **not intended for direct inference through the Hugging Face `transformers` library**.
Use [**Marian**](https://marian-nmt.github.io/docs/) for inference instead.
The repository includes the following files:
- `model.npz.best-chrf.npz` — trained Marian model checkpoint
- `tiny.decoder.yml` — decoder configuration
- `vocab.spm` — SentencePiece vocabulary
- `run_model.sh ` — Example script on how to run the model
### Supported target languages (via tags)
You control the target language by prefixing the source sentence with one of the following tags:
* `>>eng<<` → English
* `>>spa<<` → Spanish
* `>>cat<<` → Catalan
## Training data
The model was trained using **Tatoeba** parallel data, with **FLORES-200** used as the development set.
Training sentence-pair counts:
* **ca-eo**: 672,931
* **es-eo**: 4,677,945
* **eo-en**: 5,000,000
## Inference
Run decoding from inside the model directory:
```bash
cat input.epo | sed "s/^/>>cat<< /" \
marian-decoder \
-c tiny.decoder.yml \
--output output.cat \
--normalize \
-m model.npz.best-chrf.npz \
--vocabs vocab.spm vocab.spm \
--log decode.log \
--devices 0
