Beyond Lipschitz: Data-Driven Robustness via Discrete Modulus of Continuity

arXiv:2605.28729v1 Announce Type: cross Abstract: Robustness of neural networks is commonly quantified via local or global Lipschitz constants. However, Lipschitz continuity can be overly coarse or overly restrictive as global robustness measure, failing to capture nuanced, data-dependent behavior. We propose a data-driven, architecture-agnostic framework based on the discrete modulus of continuity (DMOC), a non linear generalization of Lipschitz continuity that provides a finer notion of robustness. Unlike many existing approaches, DMOC does not require access to model internals and instead e

Why this matters
Why now

The increasing deployment of neural networks in critical applications necessitates more robust and reliable methods for quantifying their behavior, moving beyond the limitations of current Lipschitz-based approaches.

Why it’s important

This work introduces a more nuanced and data-driven way to assess AI robustness, which is critical for trustworthy AI development and deployment across various industries.

What changes

The ability to quantify AI model robustness without internal access broadens the scope of robust AI evaluation and could lead to more reliable and explicable AI systems.
