# NotUrFace-AI: Deepfake Detection Model

## Model Details

### Model Description

NotUrFace-AI is a deepfake detection model designed to classify video content as real or fake. It processes first 30-50 video frames using **TensorFlow** and applies advanced machine learning techniques to identify synthetic or manipulated media. This is a passion project aimed at combating deepfake proliferation. The model is particularly useful for:

- **Social media content moderation**
- **Digital forensics**
- **Research in deepfake detection and AI ethics**

**Developer:** Sarvansh Pachori  
**Model Type:** Deepfake detection (video-based classification)  
**Finetuned from:** XceptionNet (pretrained)  

### Model Sources

- **Repository:** [sarvansh30/NotUrFace-AI](https://github.com/sarvansh30/NotUrFace-AI)  
- **Demo:** [Hugging Face Space](https://huggingface.co/spaces/sarvansh/NotUrFace-AI)  

## Usage

### Direct Use

- Classifying videos as real or fake for research, moderation, or forensic purposes.

### Downstream Use

- The model can be fine-tuned with additional deepfake datasets for improved detection on specific video types.

### Out-of-Scope Use

- The model is not intended for legal decision-making or high-stakes scenarios where absolute certainty is required.

## Bias, Risks, and Limitations

- Accuracy may vary depending on dataset bias and the quality of input videos.
- False positives or false negatives can occur, requiring human verification for critical applications.
- It may struggle with detecting highly sophisticated, unseen deepfake techniques.

### Recommendations

- Users should validate outputs in real-world applications before making critical decisions.
- Future improvements may include training on a more diverse dataset to reduce bias.

## Getting Started

Use the following code snippet to get started:

```python
from transformers import AutoModelForImageClassification, AutoTokenizer

model = AutoModelForImageClassification.from_pretrained("sarvansh/NotUrFace-AI")
tokenizer = AutoTokenizer.from_pretrained("sarvansh/NotUrFace-AI")
```

## Evaluation

### Testing Data, Factors & Metrics

#### Testing Data

The model was tested on unseen samples from the FaceForensics++ and CelebDFv2 datasets.

#### Metrics

- **Accuracy**: Measures correct classifications.
- **F1 Score**: Balances precision and recall.

### Results

| Metric              | Value  |
| ------------------- | ------ |
| Training Accuracy   | 98.44% |
| Validation Accuracy | 97.05% |
| Test Accuracy       | 95.93% |

**Disclaimer:** These results were obtained using the FaceForensics++ and CelebDFv2 datasets. Performance in real-world scenarios may vary.

### Tips for Best Performance

- The model works best with videos that have **proper lighting**.
- It only analyzes the **first 1-1.5 seconds** of a video, so ensure the clip is appropriately selected for evaluation.

## Model Architecture and Objective

- **Feature Extraction:** XceptionNet (pretrained on ImageNet) to extract spatial features.
- **Temporal Analysis:** LSTM layers to analyze frame dependencies.
- **Classification:** Fully connected layers for final binary classification.
