VeriChain Deepfake Detection Model - ViT

This repository contains the artifacts for the Vision Transformer (ViT) model fine-tuned for the task of Deepfake detection, developed as part of the VeriChain project.

The model is trained to classify an image into one of three categories: Real, AI-Generated, or Deepfake.

Repository Structure

The model artifacts in this repository are organized as follows:

• /models/vit-deepfake-model/: Contains the final, fine-tuned PyTorch model files, ready to be loaded with the transformers library.
• /models/onnx/: Contains the model converted to the ONNX format, optimized for production deployment and inference.
• /assets/: Contains visual assets for documentation, such as the confusion matrix.

How to Use (PyTorch Model)

You can use the fine-tuned PyTorch model directly with the pipeline function from the transformers library. Make sure to specify the correct subfolder.

from transformers import pipeline
from PIL import Image

# Load the image classification pipeline with your model
# The 'subfolder' parameter points to the directory containing the model files
classifier = pipeline(
    "image-classification", 
    model="einrafh/verichain-deepfake-models", 
    subfolder="models/vit-deepfake-model"
)

# Load an image you want to classify
# Make sure to replace 'path/to/your/image.jpg' with an actual image file
try:
    image = Image.open('path/to/your/image.jpg')
    results = classifier(image)
    print(results)
except FileNotFoundError:
    print("Please provide a valid path to an image file.")

# Example Output:
# [{'label': 'Deepfake', 'score': 0.9985}, {'label': 'AI Generated', 'score': 0.0010}, {'label': 'Real', 'score': 0.0005}]

Evaluation Results

The model was evaluated on a held-out test set of 2,000 images, achieving near-perfect performance.
