+# **Deep-Fake-Detector-Model**
+
+# **Overview**
+
+The **Deep-Fake-Detector-Model** is a state-of-the-art deep learning model designed to detect deepfake images. It leverages the **Vision Transformer (ViT)** architecture, specifically the `google/vit-base-patch16-224-in21k` model, fine-tuned on a dataset of real and deepfake images. The model is trained to classify images as either "Real" or "Fake" with high accuracy, making it a powerful tool for detecting manipulated media.
+
+**<span style="color:red;">Update :</span>** The previous model checkpoint was obtained using a smaller classification dataset. Although it performed well in evaluation scores, its real-time performance was average due to limited variations in the training set. The new update includes a larger dataset to improve the detection of fake images.

+
+# **Key Features**
+- **Architecture**: Vision Transformer (ViT) - `google/vit-base-patch16-224-in21k`.
+- **Input**: RGB images resized to 224x224 pixels.
+- **Output**: Binary classification ("Real" or "Fake").
+- **Training Dataset**: A curated dataset of real and deepfake images (e.g., `Hemg/deepfake-and-real-images`).
+- **Fine-Tuning**: The model is fine-tuned using Hugging Face's `Trainer` API with advanced data augmentation techniques.
+- **Performance**: Achieves high accuracy and F1 score on validation and test datasets.
+
+# **Model Architecture**
+The model is based on the **Vision Transformer (ViT)**, which treats images as sequences of patches and applies a transformer encoder to learn spatial relationships. Key components include:
+- **Patch Embedding**: Divides the input image into fixed-size patches (16x16 pixels).
+- **Transformer Encoder**: Processes patch embeddings using multi-head self-attention mechanisms.
+- **Classification Head**: A fully connected layer for binary classification.
+
+# **Training Details**
+- **Optimizer**: AdamW with a learning rate of `1e-6`.
+- **Batch Size**: 32 for training, 8 for evaluation.
+- **Epochs**: 2.
+- **Data Augmentation**:
+  - Random rotation (±90 degrees).
+  - Random sharpness adjustment.
+  - Random resizing and cropping.
+- **Loss Function**: Cross-Entropy Loss.
+- **Evaluation Metrics**: Accuracy, F1 Score, and Confusion Matrix.
+
+# **Inference with Hugging Face Pipeline**
+```python
+from transformers import pipeline
+
+# Load the model
+pipe = pipeline('image-classification', model="prithivMLmods/Deep-Fake-Detector-Model", device=0)
+
+# Predict on an image
+result = pipe("path_to_image.jpg")
+print(result)
+```
+
+# **Inference with PyTorch**
+```python
+from transformers import ViTForImageClassification, ViTImageProcessor
+from PIL import Image
+import torch
+
+# Load the model and processor
+model = ViTForImageClassification.from_pretrained("prithivMLmods/Deep-Fake-Detector-Model")
+processor = ViTImageProcessor.from_pretrained("prithivMLmods/Deep-Fake-Detector-Model")
+
+# Load and preprocess the image
+image = Image.open("path_to_image.jpg").convert("RGB")
+inputs = processor(images=image, return_tensors="pt")
+
+# Perform inference
+with torch.no_grad():
+    outputs = model(**inputs)
+    logits = outputs.logits
+    predicted_class = torch.argmax(logits, dim=1).item()
+
+# Map class index to label
+label = model.config.id2label[predicted_class]
+print(f"Predicted Label: {label}")
+```

+- **Confusion Matrix**:
+  ```
+  [[True Positives, False Negatives],
+   [False Positives, True Negatives]]
+  ```
+
+# **Dataset**
+The model is fine-tuned on the dataset, which contains:
+- **Real Images**: Authentic images of human faces.
+- **Fake Images**: Deepfake images generated using advanced AI techniques.
+
+# **Limitations**
+The model is trained on a specific dataset and may not generalize well to other deepfake datasets or domains.
+- Performance may degrade on low-resolution or heavily compressed images.
+- The model is designed for image classification and does not detect deepfake videos directly.
+
+# **Ethical Considerations**
+
+**Misuse**: This model should not be used for malicious purposes, such as creating or spreading deepfakes.
+**Bias**: The model may inherit biases from the training dataset. Care should be taken to ensure fairness and inclusivity.
+**Transparency**: Users should be informed when deepfake detection tools are used to analyze their content.
+
+# **Future Work**
+- Extend the model to detect deepfake videos.
+- Improve generalization by training on larger and more diverse datasets.
+- Incorporate explainability techniques to provide insights into model predictions.
