Working Paper: Towards a Category-theoretic Comparative Framework for Artificial General Intelligence
Summary
A working paper by Pablo de los Riscos, Fernando Corbacho, and Michael A. Arbib proposes a category-theoretic framework for describing, comparing, and analyzing different Artificial General Intelligence (AGI) architectures. The framework distinguishes between a "syntactic architecture layer," which defines how modules compose, and a "knowledge management layer," which governs information representation, transformation, and reuse. This approach treats an architecture not as a concrete algorithm but as an algebraic theory of computational interactions, presented as a free hypergraph category. The paper formalizes agent architectures as tuples $(\mathcal{G}_{A},\;\mathsf{Know}_{A},\;\Phi_{A})$ and agents as semantic interpretations of these architectures. It includes case studies on Reinforcement Learning (RL), Causal Reinforcement Learning (CRL), and Schema-Based Learning (SBL) architectures, illustrating their structural and informational properties. The authors also introduce an extended definition of architecture to incorporate explicit architectural constraints, such as Bellman-type consistency conditions, which are crucial for a faithful representation of AGI systems.
Key takeaway
For AI and Research Scientists designing or evaluating AGI systems, this category-theoretic framework provides a rigorous method to compare architectures beyond algorithmic details. You should consider adopting this formal separation of syntactic and knowledge layers to precisely characterize architectural properties and constraints. This approach enables clearer identification of commonalities, differences, and research gaps, fostering the development of more robust and generalizable AGI designs.
Key insights
Category theory offers a formal, algebraic framework to compare and analyze diverse AGI architectures structurally.
Principles
- Architectures are algebraic theories, not concrete algorithms.
- Separate syntactic structure from knowledge management.
- Properties are preserved or weakened across architectural translations.
Method
Architectures are formalized as hypergraph categories with syntactic, knowledge, and interface layers. Agents are semantic interpretations, and properties are defined structurally, informationally, and semantically via institutions and certificates.
In practice
- Use hypergraph categories to model agent architectures.
- Distinguish between syntactic and knowledge layers in design.
- Apply formal constraints to define admissible agent implementations.
