# Chest X-ray Pneumonia Detection

## Model Description


    This model is a fine-tuned Vision Transformer (ViT) for detecting pneumonia in chest X-ray images.
    It can classify chest X-rays as either NORMAL (healthy) or PNEUMONIA (showing signs of pneumonia infection).
    

## Intended Uses & Limitations

⚠️ **Important**: This model is for research and educational purposes only. It should **NOT** be used for actual medical diagnosis without proper clinical validation and oversight by qualified medical professionals.

### Intended Uses
- Research and development in medical AI
- Educational purposes for learning about medical image classification
- Proof-of-concept applications with proper disclaimers
- Academic studies and benchmarking

### Limitations
- Not clinically validated
- Should not replace professional medical diagnosis
- May have biases based on training data
- Performance may vary on different populations or imaging conditions

## Usage

```python
from transformers import AutoModelForImageClassification, AutoImageProcessor
from PIL import Image
import torch

# Load model and processor
model = AutoModelForImageClassification.from_pretrained("your-username/chest-x-ray-pneumonia-detection")
processor = AutoImageProcessor.from_pretrained("your-username/chest-x-ray-pneumonia-detection")

# Load and process image
image = Image.open("path_to_image.jpg")
inputs = processor(image, return_tensors="pt")

# Make prediction
with torch.no_grad():
    outputs = model(**inputs)
    predicted_class_id = outputs.logits.argmax().item()
    predicted_class = model.config.id2label[predicted_class_id]

print(f"Predicted class: {predicted_class}")
```

## Training Details

This model was fine-tuned from pre-trained vision transformers on medical image datasets. For detailed training information, please refer to the original model documentation.

## Evaluation

The model has been tested on held-out validation sets with the reported accuracy metrics. However, clinical evaluation and validation are required before any medical application.

## Ethical Considerations

- Medical AI models can have significant impact on human health
- Proper validation and regulatory approval required for clinical use  
- Potential for bias in training data and model predictions
- Should be used responsibly with appropriate medical oversight
