python

from peft import AutoPeftModelForCausalLM, AutoPeftModelForSequenceClassification
from transformers import AutoTokenizer

model_name = "NTaylor/bio-mobilebert-mimic-mp-lora"

# load using AutoPeftModelForSequenceClassification
model = AutoPeftModelForSequenceClassification.from_pretrained(lora_id)

# use base llama tokenizer
tokenizer = AutoTokenizer.from_pretrained("nlpie/bio-mobilebert")

# example input
text = "Clinical note..."
inputs = tokenizer(text, return_tensors="pt")
outputs = reloaded_model(**inputs)
# extract prediction from outputs based on argmax of logits
pred = torch.argmax(outputs.logits, axis = -1)
print(f"Prediction is: {pred}") # binary classification: 1 for mortality

Out-of-Scope Use

This model and LoRA weights were trained on the MIMIC-III dataset and are not intended for use on other datasets, nor be used in any real clinical setting. The experiments were conducted as a means of exploring the potential of LoRA adapters for clinical NLP tasks, and the model should not be used for any other purpose.
