Fine-tuned Vision-Language Model for Radiology Report Generation

This repository contains a fine-tuned vision-language model for generating radiology reports. It's based on the Unsloth library and utilizes the Llama-3.2-11B-Vision-Instruct model as a base.

Model Description

This model is fine-tuned on a sampled version of the ROCO radiography dataset (Radiology_mini). It's designed to assist medical professionals by providing accurate descriptions of medical images, such as X-rays, CT scans, and ultrasounds.

The fine-tuning process uses Low-Rank Adaptation (LoRA) to efficiently train the model, focusing on the language layers while keeping the vision layers frozen. This approach minimizes the computational resources required for fine-tuning while achieving significant performance improvements.

Usage

To use this model, you'll need the Unsloth library:

pip install unsloth

Then, you can load the model and tokenizer:

python

from unsloth import FastVisionModel

model, tokenizer = FastVisionModel.from_pretrained("awaliuddin/unsloth_finetune", load_in_4bit=True)
FastVisionModel.for_inference(model)

python

from PIL import Image

image = Image.open("path/to/your/image.jpg") # Replace with your image path
instruction = "You are an expert radiographer. Describe accurately what you see in this image."
messages = [ {"role": "user", "content": [ {"type": "image"}, {"type": "text", "text": instruction} ]} ]

input_text = tokenizer.apply_chat_template(messages, add_generation_prompt=True) inputs = tokenizer(image, input_text, add_special_tokens=False, return_tensors="pt").to("cuda")

from transformers import TextStreamer

text_streamer = TextStreamer(tokenizer, skip_prompt=True) _ = model.generate(**inputs, streamer=text_streamer, max_new_tokens=128, use_cache=True, temperature=1.5, min_p=0.1)

Training Details

Base Model: Llama-3.2-11B-Vision-Instruct
Dataset: Radiology_mini (sampled from ROCO radiography dataset)
Fine-tuning Method: LoRA (language layers only)
Optimizer: AdamW 8-bit
Learning Rate: 2e-4

Limitations

This model is trained on a limited dataset and might not generalize well to all types of medical images.
The generated reports should be reviewed by qualified medical professionals before being used for diagnostic purposes.
