A Typed Tensor Language for Federated Learning

arXiv:2605.21103v1 Announce Type: new Abstract: Federated learning and analytics are often described as collections of separate protocols, even when they share the same mathematical form: client-local tensor computation, mergeable aggregation into shared state, and shared-only post-processing. We introduce a typed tensor language that formalizes this structure. The language distinguishes federated tensors, whose records are partitioned across clients along a tracked record axis, from shared tensors, which are available globally. Its semantics are defined by comparison with a virtual global ten

Why this matters
Why now

The increasing complexity and privacy demands of distributed AI systems like federated learning necessitate new formalisms to ensure correctness and efficiency.

Why it’s important

This development is important for enabling more robust, secure, and privacy-preserving AI development, particularly in sensitive sectors, by providing a structured approach to federated learning.

What changes

The formalization of federated learning into a typed tensor language provides a standardized and verifiable framework for its implementation, potentially accelerating its adoption and ensuring its reliability.
