## VHHBERT

VHHBERT is a RoBERTa-based model pre-trained on two million VHH sequences in [VHHCorpus-2M](https://huggingface.co/datasets/COGNANO/VHHCorpus-2M).
VHHBERT has the same model parameters as RoBERTa<sub>BASE</sub>, except that it used positional embeddings with a length of 185 to cover the maximum sequence length of 179 in VHHCorpus-2M.
Further details on VHHBERT are described in our paper "[A SARS-CoV-2 Interaction Dataset and VHH Sequence Corpus for Antibody Language Models](https://arxiv.org/abs/2405.18749).”

## Usage

The model and tokenizer can be loaded using the `transformers` library.

```python
from transformers import BertTokenizer, RobertaModel
tokenizer = BertTokenizer.from_pretrained("COGNANO/VHHBERT")
model = RobertaModel.from_pretrained("COGNANO/VHHBERT")
```
