## Model Details

### Model Description

This model is fine-tuned from [stable-diffusion-v1-5](https://huggingface.co/runwayml/stable-diffusion-v1-5) on 110,000 image-text pairs from the MIMIC dataset using the Bias tuning PEFT method. Under this fine-tuning strategy, fine-tune only the bias weights in the U-Net while keeping everything else frozen.

## Direct Use

This model can be directly used to generate realistic medical images from text prompts. 


## How to Get Started with the Model

```python
import os
from safetensors.torch import load_file
from diffusers.pipelines import StableDiffusionPipeline

pipe = StableDiffusionPipeline.from_pretrained(sd_folder_path, revision="fp16")
exp_path = os.path.join('unet', 'diffusion_pytorch_model.safetensors')
state_dict = load_file(exp_path)

# Load the adapted U-Net
pipe.unet.load_state_dict(state_dict, strict=False)
pipe.to('cuda:0')

# Generate images with text prompts

TEXT_PROMPT = "No acute cardiopulmonary abnormality."
GUIDANCE_SCALE = 4
INFERENCE_STEPS = 75

result_image = pipe(
        prompt=TEXT_PROMPT,
        height=224,
        width=224,
        guidance_scale=GUIDANCE_SCALE,
        num_inference_steps=INFERENCE_STEPS,
    )

result_pil_image = result_image["images"][0]
```


## Training Details

### Training Data

This model has been fine-tuned on 110K image-text pairs from the MIMIC dataset. 

### Training Procedure

The training procedure has been described in detail in Section 4.3 of this [paper](https://arxiv.org/abs/2305.08252).

#### Metrics

This model has been evaluated using the Fréchet inception distance (FID) Score on MIMIC dataset.

## Environmental Impact

Using Parameter-Efficient Fine-Tuning potentially causes **lesser** harm to the environment since we fine-tune a significantly lesser number of parameters in a model. This results in much lesser computing and hardware requirements.
