New research contrasts Fisher Simplicity in KANs and MLPs

By PulseAugur Editorial · [1 sources] ·

A new paper explores the concept of Fisher Simplicity in relation to Kolmogorov-Arnold Networks (KANs) and multilayer perceptrons (MLPs). The research investigates when architectural notions of simplicity, such as zero basis coefficients in KANs or dead rectified linear units (ReLUs) in MLPs, align with the statistical definition of Fisher simplicity. The study finds that while dead ReLUs in MLPs correspond to Fisher simplicity, this is not the case for fixed-basis KANs. For KANs, Fisher simplicity depends on data propagation through the network, and coefficient magnitude alone is not a reliable criterion for pruning. AI

IMPACT This research provides theoretical insights into the interpretability and pruning criteria for KANs, potentially influencing future neural network design.

    Fisher Simplicity in Kolmogorov-Arnold Networks and Multilayer Perceptrons

    arXiv:2609.32503v2 Announce Type: replace Abstract: Kolmogorov-Arnold Networks (KANs) are motivated in part by interpretability: their learned edge functions can be inspected, pruned, and reduced to symbolic structure. In a fixed-basis KAN, this makes a small or zero basis coeffi…
