# Florence-2 DOCCI-FT LoRA Adapter

This repository contains a LoRA adapter trained on google/docci for the Florence-2-base-FT model. It's designed to enhance the model's captioning capabilities, providing more detailed captions.

## Usage

To use this LoRA adapter, you'll need to load it along with the Florence-2-base model using the PEFT library. Here's an example of how to use it:

```python
from PIL import Image
from transformers import AutoProcessor, AutoModelForCausalLM
from peft import PeftModel, PeftConfig
import requests

def caption(image):
  base_model = AutoModelForCausalLM.from_pretrained("microsoft/Florence-2-base-ft", trust_remote_code=True)
  processor = AutoProcessor.from_pretrained("microsoft/Florence-2-base-ft", trust_remote_code=True)
  prompt = "<MORE_DETAILED_CAPTION>"
  adapter_name = "NikshepShetty/Florence-2-DOCCI-FT"
  model = PeftModel.from_pretrained(base_model, adapter_name, trust_remote_code=True)
  inputs = processor(text=prompt, images=image, return_tensors="pt")

  generated_ids = model.generate(
      input_ids=inputs["input_ids"],
      pixel_values=inputs["pixel_values"],
      max_new_tokens=1024,
      do_sample=False,
      num_beams=3
  )
  generated_text = processor.batch_decode(generated_ids, skip_special_tokens=False)[0]

  parsed_answer = processor.post_process_generation(generated_text, task="<MORE_DETAILED_CAPTION>", image_size=(image.width, image.height))

  print(parsed_answer)

url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/tasks/car.jpg?download=true"
image = Image.open(requests.get(url, stream=True).raw)
caption(image)
```


This code demonstrates how to:
1. Load the base Florence-2 model
2. Load the LoRA adapter
3. Process an image and generate a detailed caption

Note: Make sure you have the required libraries installed: transformers, peft, einops, flash_attn, timm, Pillow, and requests.

## Evaluation results

Our LoRA adapter shows significant improvements over the base Florence-2 model across all metrics for MORE_DETAILED_CAPTION tag:

| Metric  | Base Model | Adapted Model | Improvement |
|---------|------------|---------------|-------------|
| METEOR  | 0.205      | 0.261         | +27.3%      |
| BLEU    | 0.124      | 0.208         | +67.7%      |
| CIDEr   | 0.023      | 0.072         | +213.0%     |
| CAPTURE | 0.529      | 0.565         | +6.8%       |
| ROUGE-L | 0.265      | 0.280         | +5.7%       |

These results demonstrate that our LoRA adapter significantly enhances the image captioning capabilities of the Florence-2 base model, particularly in generating more detailed and accurate captions.
