<h2>GatorTronS overview </h2> |
|
|
|
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 |
|
|
|
<h2>22B synthetic clinical text description</h2> |
|
|
|
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 |
