GatorTronS overview

Developed by a joint effort between the University of Florida and NVIDIA, GatorTronS is a clinical language model of 345 million parameters, pre-trained using a BERT architecure implemented in the Megatron package (https://github.com/NVIDIA/Megatron-LM).

GatorTronS is pre-trained using a dataset consisting of:

  • 22B synthetic clinical words generated by GatorTronGPT (a Megatron GPT-3 model)
  • 6.1B words from PubMed CC0,
  • 2.5B words from WikiText,
  • 0.5B words of de-identified clinical notes from MIMIC-III

The Github for GatorTronGPT is at : https://github.com/uf-hobi-informatics-lab/GatorTronGPT

This model is converted to Hugginface from : https://catalog.ngc.nvidia.com/orgs/nvidia/teams/clara/models/gatortron_s

22B synthetic clinical text description

We sampled the beginning 15 tokens from all sections of the de-identified notes from the MIMIC III database and generated approximately 8 million prompts. We also tried several random seeds in GatorTronGPT to generate multiple documents from one prompt. We controlled GatorTronGPT to generate a maximum length of 512 tokens. We apply GatorTronGPT to generate a total of 22 billion words of synthetic clinical text. Detailed information is provided in the GatorTronGPT paper: https://arxiv.org/abs/2305.13523

How to use

from transformers import AutoModel, AutoTokenizer, AutoConfig

tokinizer= AutoTokenizer.from_pretrained('UFNLP/gatortronS')
config=AutoConfig.from_pretrained('UFNLP/gatortronS')
mymodel=AutoModel.from_pretrained('UFNLP/gatortronS')

encoded_input=tokinizer("Bone scan:  Negative for distant metastasis.", return_tensors="pt")
encoded_output = mymodel(**encoded_input)
print (encoded_output)
