# BarcodeBERT for Taxonomic Classification

A pre-trained transformer model for inference on insect DNA barcoding data.  

[Colab](https://drive.google.com/file/d/1MUEQVHIOX2ks7tLsMoQtNlbvsbSuYgs1/view?usp=sharing)

To use **BarcodeBERT** as a feature extractor:

```python
from transformers import AutoTokenizer, AutoModel

# Load the tokenizer
tokenizer = AutoTokenizer.from_pretrained("bioscan-ml/BarcodeBERT", trust_remote_code=True)

#Load the model 
model = AutoModel.from_pretrained("bioscan-ml/BarcodeBERT", trust_remote_code=True)

# Sample sequence
dna_seq = 'ACGCGCTGACGCATCAGCATACGA'

# Tokenize
input_seq = tokenizer(dna_seq, return_tensors = 'pt')['input_ids']

# Pass through the model
output = model(input_seq)['hidden_states'][-1]

# Compute Global Average Pooling 
features = output.mean(1)
```
