Quick Start

Prerequisites

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

Local Development

1. Clone and setup:

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:

# 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:

cd frontend
npm install
npm run dev

4. Full stack with Docker:

docker-compose up --build

Production Deployment

1. Build optimized models:

python scripts/quantization.py --model_path models/checkpoints/best_model.pth --config_path configs/optimization_config.json

2. Deploy to Kubernetes:

kubectl apply -f infrastructure/kubernetes/
kubectl rollout status deployment/emotia-backend

Advanced AI Models

CLIP-Based Fusion Architecture

# 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

# 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

# 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)
