arXiv:2607.07778v1 Announce Type: new Abstract: Bubeck, Li and Nagaraj conjectured that, for generic data, any two-layer neural network with $m$ neurons that fits $n$ noisy labels must have Lipschitz constant at least of order $\sqrt{n/m}$, with no restriction on the size of the weights. Bubeck and Sellke proved a universal version of this law for Lipschitz-parameterized classes, but under a polynomial bound on the parameters; at depth three that boundedness hypothesis is genuinely necessary. The two-layer unbounded-weight case requires a different argument. We prove the conjectured law, up to
This research, following prior conjectures and partial proofs, provides a theoretical underpinning for understanding robustness in neural networks, a critical area for AI reliability and deployment.
A strategic reader should care because understanding the fundamental limits and properties of neural network robustness is crucial for developing explainable, secure, and reliable AI systems, especially in high-stakes applications.
The theoretical proof clarifies a conjectured 'law of robustness' for two-layer neural networks, refining our understanding of how network architecture and noisy data interact with model stability.
