Axiomatizing Neural Networks via Pursuit of Subspaces

arXiv:2605.20534v1 Announce Type: new Abstract: While deep neural networks have achieved remarkable success across a wide range of domains, their underlying mechanisms remain poorly understood, and they are often regarded as black boxes. This gap between empirical performance and theoretical understanding poses a challenge analogous to the pre-axiomatic stage of classical geometry. In this work, we introduce the Pursuit of Subspaces (PoS) hypothesis, an axiomatic framework that formulates neural network behavior through a set of geometric postulates. These axioms, together with their derived c

Why this matters
Why now

The increasing complexity and pervasive application of deep neural networks necessitate a deeper theoretical understanding that extends beyond empirical successes, pushing researchers to develop foundational frameworks.

Why it’s important

A foundational, axiomatic understanding of neural networks could unlock new capabilities, improve reliability, and accelerate development by moving beyond empirical trial-and-error.

What changes

The introduction of an axiomatic framework like Pursuit of Subspaces signals a potential methodological shift towards more theoretically grounded AI research, moving away from 'black box' intuitions.
