# 🛣️ Vehicle Anomaly Detection System

An advanced machine learning-powered anomaly detection system for GPS tracking data with a beautiful Gradio interface.

## 🚀 Features

- **Multiple ML Models**: Ensemble of Isolation Forest, One-Class SVM, and LSTM Autoencoder
- **Beautiful UI**: Modern Gradio interface with interactive visualizations
- **Real-time Processing**: Handles up to 2000 GPS points with detailed analysis
- **Comprehensive Output**: Point-by-point analysis, risk factors, and JSON export
- **Interactive Maps**: GPS route visualization with anomaly highlighting
- **Performance Analytics**: Speed, altitude, and confidence distribution charts

## 📊 Processing Performance

- **CPU-only processing**: 45-90 seconds for 2000 samples
- **HuggingFace Spaces ready**: Optimized for cloud deployment
- **Memory efficient**: Handles large datasets with rolling window processing

## 🔧 Installation

### Local Installation

```bash
# Clone or download the project
cd anomaly

# Install dependencies
pip install -r requirements.txt

# Run the Gradio app
python gradio_app.py
```

### HuggingFace Spaces Deployment

1. Create a new Space on HuggingFace
2. Upload all files including the `models/` directory
3. Set `app_file` to `app.py`
4. The app will automatically launch

## 📁 Input Format

Your CSV file must contain these columns:

| Column | Description | Range |
|--------|-------------|-------|
| `randomized_id` | Vehicle identifier | Any string |
| `lat` | Latitude | -90 to 90 |
| `lng` | Longitude | -180 to 180 |
| `spd` | Speed (km/h) | 0 to 300 |
| `azm` | Azimuth/heading (degrees) | 0 to 360 |
| `alt` | Altitude (meters) | Any number |

### Sample Data

```csv
randomized_id,lat,lng,spd,azm,alt
VEHICLE001,40.7128,-74.0060,45.5,90.0,100.0
VEHICLE001,40.7138,-74.0070,48.2,92.0,102.0
VEHICLE002,40.7500,-73.9800,35.2,180.0,90.0
```

**Maximum**: 2000 samples per upload
**Minimum**: 5 samples required
