# COMET-partial

This model is based on [COMET-early-exit](https://github.com/zouharvi/COMET-early-exit), which is a fork but not compatible with original Unbabel's COMET.
To run the model, you need to first install this version of COMET either with:
```bash
pip install "git+https://github.com/zouharvi/COMET-early-exit#egg=comet-early-exit&subdirectory=comet_early_exit"
```
or in editable mode:
```bash
git clone https://github.com/zouharvi/COMET-early-exit.git
cd COMET-early-exit
pip3 install -e comet_early_exit
```


This model is described in the appendix in the paper.
It is able to score even *incomplete* translations (i.e. prefixes of translations):
```python
model = comet_early_exit.load_from_checkpoint(comet_early_exit.download_model("zouharvi/COMET-partial"))
data = [
    {
        "src": "Can I receive my food in 10 to 15 minutes?",
        "mt": "Mohl bych",
    },
    {
        "src": "Can I receive my food in 10 to 15 minutes?",
        "mt": "Mohl bych dostat jídlo",
    },
    {
        "src": "Can I receive my food in 10 to 15 minutes?",
        "mt": "Mohl bych dostat jídlo během 10 či 15 minut?",
    }
]
model_output = model.predict(data, batch_size=8, gpus=1)
print("scores", model_output["scores"])
```
Outputs (formatted):
```
scores 89.18  86.52  89.20
```

This model is based on the work [Early-Exit and Instant Confidence Translation Quality Estimation](http://arxiv.org/abs/2502.14429) which can be cited as:
