## Quick Start

### Prerequisites
- Python 3.9+
- Node.js 18+
- Docker & Docker Compose
- Kubernetes cluster (for production)

### Local Development

1. **Clone and setup:**
```bash
git clone https://github.com/Manavarya09/Multi-Modal-Emotion-Intent-Intelligence-for-Video-Calls.git
cd Multi-Modal-Emotion-Intent-Intelligence-for-Video-Calls
```

2. **Backend setup:**
```bash
# Install Python dependencies
pip install -r requirements.txt

# Start Redis
docker run -d -p 6379:6379 redis:7-alpine

# Run advanced training
python scripts/advanced/advanced_trainer.py --config configs/training_config.json
```

3. **Frontend setup:**
```bash
cd frontend
npm install
npm run dev
```

4. **Full stack with Docker:**
```bash
docker-compose up --build
```

### Production Deployment

1. **Build optimized models:**
```bash
python scripts/quantization.py --model_path models/checkpoints/best_model.pth --config_path configs/optimization_config.json
```

2. **Deploy to Kubernetes:**
```bash
kubectl apply -f infrastructure/kubernetes/
kubectl rollout status deployment/emotia-backend
```

## Advanced AI Models

### CLIP-Based Fusion Architecture
```python
# Advanced fusion with contrastive learning
model = AdvancedFusionModel({
    'vision_model': 'resnet50',
    'audio_model': 'wav2vec2',
    'text_model': 'bert-base',
    'fusion_dim': 512,
    'use_clip': True,
    'uncertainty_estimation': True
})
```

### Distributed Training
```python
# Multi-GPU training with mixed precision
trainer = AdvancedTrainer(config)
trainer.train_distributed(
    model=model,
    train_loader=train_loader,
    num_epochs=100,
    use_amp=True,
    gradient_clip_val=1.0
)
```

### Real-Time WebSocket API
```python
# Streaming analysis with monitoring
@app.websocket("/ws/analyze/{session_id}")
async def websocket_analysis(websocket: WebSocket, session_id: str):
    await websocket.accept()
    analyzer = RealtimeAnalyzer(model, session_id)

    async for frame_data in websocket.iter_json():
        result = await analyzer.analyze_frame(frame_data)
        await websocket.send_json(result)
```

## Advanced Frontend Features

- **Emotion Space**: Valence-Arousal-Dominance 3D scatter plot
- **Intent Radar**: Real-time intent probability visualization
- **Modality Fusion**: Interactive contribution weight display

### Progressive Web App (PWA)

// Real-time video capture and streaming
const stream = await navigator.mediaDevices.getUserMedia({
  video: { width: 1280, height: 720, frameRate: 30 },
  audio: { sampleRate: 16000, channelCount: 1 }
});

const ws = new WebSocket('ws://localhost:8080/ws/analyze/session_123');
