bio-lm

Model description

This model is a RoBERTa base pre-trained model that was further trained using a masked language modeling task on a compendium of english scientific textual examples from the life sciences using the BioLang dataset.

Intended uses & limitations

How to use

The intended use of this model is to be fine-tuned for downstream tasks, token classification in particular.

To have a quick check of the model as-is in a fill-mask task:

python

from transformers import pipeline, RobertaTokenizerFast
tokenizer = RobertaTokenizerFast.from_pretrained('roberta-base', max_len=512)
text = "Let us try this model to see if it <mask>."
fill_mask = pipeline(
    "fill-mask",
    model='EMBO/bio-lm',
    tokenizer=tokenizer
)
fill_mask(text)

Limitations and bias

This model should be fine-tuned on a specifi task like token classification. The model must be used with the roberta-base tokenizer.

Training data

The model was trained with a masked language modeling taskon the BioLang dataset wich includes 12Mio examples from abstracts and figure legends extracted from papers published in life sciences.

Training procedure

The training was run on a NVIDIA DGX Station with 4XTesla V100 GPUs.
