Federation Layer

The Federation Layer enables decentralized learning. It allows multiple domains to share knowledge without sharing raw data.

FederationCoordinator

The central component that manages network health. - Membership: Dynamic peer discovery. - Routing: Intelligent update routing. - Trust: Managing reputation scores.

Packet Types

We use different packet types for specific data exchanges:

1. PathPack (Knowledge Transfer)

Contains discovered causal paths and their weights. - Ensures both peers are talking about the same data structure. - Includes performance statistics and audit trails.

2. EdgeDelta (Incremental Updates)

Smaller packets for bandwidth-constrained environments. - Only transmits edges that have changed. - Includes pruning commands for spurious edges.

3. PolicyPack (Meta-Learning)

Sharing how to learn, not just what was learned. - Transmits Bandit parameters and DRG thresholds.

Privacy & Trust Security

The framework ensures safety through four mechanisms:

Trust Scoring Peers are rated based on the quality of their updates. Low-quality peers are ignored.
Privacy Guard Differential Privacy noise is injected into weights. No raw data ever leaves the local domain.
Packet Validation Cryptographic signatures ensure packets aren't tampered with.
Selective Sharing Updates are only sent to peers with sufficient Trust Score.
