Federated Learning: Privacy-Preserving Distributed AI

Federated learning enables machine learning models to be trained across multiple decentralized devices or servers holding local data samples, without exchanging the actual data. This privacy-preserving approach allows organizations and individuals to collaboratively train AI models while keeping sensitive data local.

What is Federated Learning?

Allows computation on encrypted data without decryption. Model updates

Trusted Execution Environments

Hardware-based secure enclaves that protect model training and aggregation from malicious clients or servers. These provide hardware-level security guarantees.

Frequently asked questions

How does federated learning preserve privacy?

Federated learning preserves privacy by keeping raw data on client devices. Only model updates (gradients or weights) are sent to the server, not the actual data.

Federated learning preserves privacy by what techniques?

Federated learning preserves privacy through techniques like differential privacy, secure aggregation, or homomorphic encryption, which combine to provide strong guarantees while enabling collaborative training.

What is the difference between federated learning and distributed training?

Distributed training typically involves multiple workers with access to all training data, coordinating through a parameter server. Federated learning involves clients with their own private data that cannot be shared.

Distributed training assumes what about the data?

Distributed training assumes data can be partitioned and distributed across workers, whereas federated learning maintains data locality – it remains on the client devices.
