How It Works

1. Initial model distribution: You start by sending a base model to participating devices.

2. Local training: Each device trains the model using its local data.

3. Model updates: Devices send only the updated model parameters back to a central server.

4. Aggregation: The server combines these updates to improve the global model.

5. Iteration: The process repeats until the model reaches desired performance levels.

Key Benefits

Federated learning offers several advantages over traditional centralized approaches:

• Enhanced Privacy: Raw data never leaves the local device, significantly reducing privacy risks.

• Reduced Data Transfer: Only model updates are transmitted, minimizing bandwidth requirements.

• Improved Model Performance: Access to diverse, real-world data often leads to more robust models.

• Regulatory Compliance: This approach helps you meet data protection regulations like GDPR.

By embracing federated learning, you can harness the power of collaborative AI while maintaining strict data privacy standards. This breakthrough technique is reshaping how organizations approach machine learning in an increasingly privacy-conscious world.
