TL;DR
A new draft introduces a machine learning framework built with Rust, grounded in category theory principles. It aims to make ML systems more structured and mathematically rigorous. The work is ongoing, with community feedback encouraged.
A new working draft presents a machine learning framework built with Rust, leveraging category theory to structure the pipeline of transformations and models. This approach aims to make ML systems more explicit, maintainable, and mathematically grounded, emphasizing practical engineering over abstract theory.
The draft, titled ‘Category Theory for Tiny ML in Rust,’ is a collaborative effort by Hamze Ghalebi and Farzad Jafarranmani. It develops a small, explicit ML system where domain objects are represented as Rust types, and transformations as typed functions, following category theory principles.
The project treats category theory not just as a mathematical abstraction but as an engineering framework, turning theoretical concepts into executable Rust code. The current version is a work in progress, with chapters, examples, and terminology still evolving. The source code and draft are publicly accessible on GitHub, inviting community feedback.
Why It Matters
This development is significant because it bridges advanced mathematical concepts with practical software engineering, potentially leading to more transparent, verifiable, and maintainable ML systems. Using Rust ensures safety and performance, making this approach relevant for production environments where reliability is critical.
It also exemplifies how category theory can be operationalized in software, moving beyond abstract mathematics into concrete engineering tools, which could influence future ML framework design and educational approaches.

Background
Traditional ML frameworks focus on numerical computation and often lack explicit structural representations. Recent efforts in formal methods and mathematical rigor aim to improve system reliability and interpretability. This draft continues that trend by integrating category theory into ML pipeline design, inspired by prior work in denotational semantics and type theory.
The project builds on the idea that ML pipelines can be viewed as compositions of objects and transformations—core concepts in category theory—making the structure of models more explicit and easier to reason about.
“We are turning mathematical and ML ideas into understandable, typed, maintainable systems using Rust and category theory.”
