Model Details
Model Description
This model is fine-tuned from stable-diffusion-v1-5 on 110,000 image-text pairs from the MIMIC dataset using the Norm-tuning PEFT method. Under this fine-tuning strategy, fine-tune only the normalization weightsin the U-Net while keeping everything else frozen.

How to Get Started with the Model
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]

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.
