# biolinkbert-mednli

This model is a fine-tuned version of [michiyasunaga/BioLinkBERT-large](https://huggingface.co/michiyasunaga/BioLinkBERT-large) on [MedNLI](https://physionet.org/content/mednli/1.0.0/).
It achieves the following results on the evaluation set:
```
{
    "eval_accuracy": 0.8788530230522156,
    "eval_loss": 0.7843484878540039,
    "eval_runtime": 39.7009,
    "eval_samples": 1395,
    "eval_samples_per_second": 35.138,
    "eval_steps_per_second": 1.108
}
```

The accuracy for the test set is
```
{
    "eval_accuracy": 0.8607594966888428,
    "eval_loss": 0.879707932472229,
    "eval_runtime": 27.4404,
    "eval_samples": 1395,

    "1": "neutral",
    "2": "contradiction"
  },
```

## Training procedure

This model checkpoint is made by [mednli.py](https://huggingface.co/cnut1648/biolinkbert-mednli/blob/main/mednli.py) by the following command:
```shell
