Model Card for Model ID

This is an official model checkpoint for Asclepius-Llama2-7B (arxiv). This model is an enhanced version of Asclepius-7B, by replacing the base model with Llama-2 and increasing the max sequence length to 4096.

UPDATE

2024.01.10

• Asclepius-R, the variant of Asclepius that trained on MIMIC-III discharge summaries, is now available on Physionet!

How to Get Started with the Model

prompt = """You are an intelligent clinical languge model.
Below is a snippet of patient's discharge summary and a following instruction from healthcare professional.
Write a response that appropriately completes the instruction.
The response should provide the accurate answer to the instruction, while being concise.

[Discharge Summary Begin]
{note}
[Discharge Summary End]

[Instruction Begin]
{question}
[Instruction End] 
"""

Training Details

Training Data

https://huggingface.co/datasets/starmpcc/Asclepius-Synthetic-Clinical-Notes

Training Procedure

• Initial training was conducted using causal language modeling on synthetic clinical notes.
• It was then fine-tuned with clinical instruction-response pairs.
• For a comprehensive overview of our methods, our upcoming paper will serve as a resource.

Training Hyperparameters

• We followed config used in Stanford Alpaca

Speeds, Sizes, Times

• Pre-Training (1 epoch): 1h 7m with 8x A100 80G
• Instruction Fine-Tuning (3 epoch): 6h 47m with 8x A100 80G
