New INR framework fuses MLP and KAN for improved signal representation

Researchers have developed a new Implicit Neural Representation (INR) framework that fuses a Multi-Layer Perceptron (MLP) with a Kolmogorov-Arnold Network (KAN) to better model multidimensional signals. This hybrid approach addresses the spectral bias of traditional MLPs, which tend to favor low frequencies, by allowing the KAN branch to capture high-frequency details. The framework integrates discrete wavelet transforms to decompose and fuse outputs from both branches, encouraging complementary frequency-oriented modeling. Experiments across various signal types, including images, volumes, and light-fields, show improved reconstruction fidelity. AI

IMPACT This research could lead to more accurate and detailed modeling of complex data, potentially benefiting fields that rely on high-fidelity signal reconstruction.
