New Bounds Reveal Kolmogorov-Arnold Networks' Geometric Complexity Advantage

By PulseAugur Editorial · [1 sources] ·

Researchers have established tight asymptotic bounds on the maximum number of linear regions for continuous piecewise-linear Kolmogorov-Arnold Networks (KANs). These bounds, which include both upper and lower limits, determine the growth order in terms of affine segments per edge. The study also compares the expressive power of CPWL KANs with ReLU networks, demonstrating a polynomial advantage for KANs under certain conditions, which provides a basis for understanding their complexity and guiding architectural choices. AI

IMPACT Provides theoretical insights into the expressive power of KANs compared to ReLU networks, potentially guiding future architectural designs.

    Tight Asymptotic Bounds on the Maximum Number of Linear Regions of Piecewise-Linear Kolmogorov--Arnold networks

    arXiv:2611.07973v1 Announce Type: new Abstract: Schoots et al.~\citep{schoots2025relating} (AISTATS 2025) established a generally loose upper bound on the number of linear regions of continuous piecewise-linear (CPWL) Kolmogorov--Arnold networks (KANs), without providing a lower …
