What it is
The paper presents a framework that connects Kolmogorov-Arnold networks (KANs) to scientific discovery across three tasks: identifying relevant features, revealing modular structure, and discovering symbolic formulas. It introduces MultKAN (1), KANs with multiplication nodes; kanpiler (2), a compiler that turns symbolic formulas into KANs; and a tree converter (3) that renders a KAN (or any neural network) as a tree graph. Using these tools, the authors demonstrate KANs recovering physical laws including conserved quantities, Lagrangians, symmetries, and constitutive laws.
Why it matters
The authors frame AI and science as incompatible today because AI rests on connectionism while science depends on symbolism. By making a KAN compilable to and from symbolic formulas, the framework lets scientific knowledge be injected into the network (science to KAN) and lets human-readable structure be extracted back out (KAN to science), a bidirectional path between the two. That addresses the opacity that normally keeps neural function approximators separate from explicit scientific expressions.
