# Federated Learning for Privacy-Preserving Financial Data Generation with RAG Integration

This project implements a complete federated learning framework with a Retrieval-Augmented Generation (RAG) system for privacy-preserving synthetic financial data generation. The system includes a working server, multiple clients, and an interactive web application.

## Live Demo

**Try it now**: [Hugging Face Spaces](https://huggingface.co/spaces/ArchCoder/federated-credit-scoring)

## Features

- **Complete Federated Learning System**: Working server, clients, and web interface
- **Real-time Predictions**: Get credit score predictions from the federated model
- **Interactive Web App**: Beautiful Streamlit interface with demo and real modes
- **Client Simulator**: Built-in client simulator for testing
- **Privacy-Preserving**: No raw data sharing between participants
- **Educational**: Learn about federated learning concepts
- **Production Ready**: Docker and Kubernetes deployment support

## Quick Start

### Option 1: Try the Demo
1. Visit the [Live Demo](https://huggingface.co/spaces/ArchCoder/federated-credit-scoring)
2. Enter customer features and get predictions
3. Learn about federated learning

### Option 2: Run Locally (Complete System)

1. **Install Dependencies**
```bash
# Create virtual environment
python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install dependencies
pip install -r requirements-full.txt
```

2. **Start the Federated Server**
```bash
python -m src.main --mode server --config config/server_config.yaml
```

3. **Start Multiple Clients** (in separate terminals)
```bash
python -m src.main --mode client --config config/client_config.yaml
```

4. **Run the Web Application**
```bash
streamlit run webapp/streamlit_app.py
```

5. **Test the Complete System**
```bash
python test_complete_system.py
```

## How to Use

### Web Application Features:
- **Demo Mode**: Works without server (perfect for HF Spaces)
- **Real Mode**: Connects to federated server for live predictions
- **Client Simulator**: Start/stop client participation
- **Training Progress**: Real-time monitoring of federated rounds
- **Server Health**: Check server status and metrics
- **Educational Content**: Learn about federated learning

### Federated Learning Process:
1. **Server Initialization**: Global model is created
2. **Client Registration**: Banks register with the server
3. **Local Training**: Each client trains on their local data
4. **Model Updates**: Clients send model updates (not data) to server
5. **Aggregation**: Server aggregates updates using FedAvg
6. **Global Model**: Updated model is distributed to all clients
7. **Prediction**: Users can get predictions from the global model

## Configuration

### Server Configuration (`config/server_config.yaml`)
```yaml
# API server configuration
api:
  host: "0.0.0.0"
  port: 8080

# Federated learning configuration
federated:
  min_clients: 2
  rounds: 10

# Model configuration
model:
  input_dim: 32
  hidden_layers: [128, 64]
```

### Client Configuration (`config/client_config.yaml`)
```yaml
client:
  id: "client_1"
  server_url: "http://localhost:8080"
  data:
    batch_size: 32
    input_dim: 32
```

## Testing

Run the complete system test:
```bash
python test_complete_system.py
```

This will test:
- Server health
- Client registration
- Training status
- Prediction functionality
