Informational Frustration in Neural Manifolds: Shannon Bottlenecks and the Limits of Learnability

arXiv:2606.30512v1 Announce Type: new Abstract: Why overparameterised deep networks generalise so remarkably well remains one of the most stubborn open questions in machine learning theory. Classical frameworks like VC dimension and Rademacher complexity predict catastrophic overfitting in modern models, leaving a massive theoretical gap between theory and reality. In this paper, we bridge this divide by introducing a unified framework that links information theory, topology, and statistical mechanics to map the hard limits of deep learning. Central to our approach is the Entropic Learnability

Why this matters
Why now

This research is published as the theoretical understanding of deep learning struggles to keep pace with its empirical success, creating a significant gap for foundational work.

Why it’s important

A unified framework linking information theory, topology, and statistical mechanics could unlock a deeper understanding of deep learning's fundamental limits and capabilities, guiding future AI development.

What changes

The theoretical landscape for machine learning shifts to incorporate information-theoretic and topological constraints, potentially revealing new bottlenecks and optimal architectures.
