## Model Description

<!-- Provide a longer summary of what this model is/does. -->
LoRA adapter weights from fine-tuning [BioMobileBERT](https://huggingface.co/nlpie/bio-mobilebert) on the MIMIC-III mortality prediction task. The [PEFT](https://github.com/huggingface/peft) was used and the model was trained for a maximum of 5 epochs with early stopping, full details can be found at the [github repo](https://github.com/nlpie-research/efficient-ml).

<!-- # Uses -->

<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->

<!-- ## Direct Use -->

<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->
<!-- If the user enters content, print that. If not, but they enter a task in the list, use that. If neither, say "more info needed." -->




<!-- ## Downstream Use [Optional] -->

<!-- This section is for the model use when fine-tuned for a task, or when plugged into a larger ecosystem/app -->
<!-- If the user enters content, print that. If not, but they enter a task in the list, use that. If neither, say "more info needed." -->
 

# How to Get Started with the Model

```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 section addresses misuse, malicious use, and uses that the model will not work well for. -->
<!-- If the user enters content, print that. If not, but they enter a task in the list, use that. If neither, say "more info needed." -->

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.


<!-- # Bias, Risks, and Limitations -->

<!-- This section is meant to convey both technical and sociotechnical limitations. -->

<!-- Significant research has explored bias and fairness issues with language models (see, e.g., [Sheng et al. (2021)](https://aclanthology.org/2021.acl-long.330.pdf) and [Bender et al. (2021)](https://dl.acm.org/doi/pdf/10.1145/3442188.3445922)). Predictions generated by the model may include disturbing and harmful stereotypes across protected classes; identity characteristics; and sensitive, social, and occupational groups. -->
