Researchers have developed an enhanced version of Kolmogorov-Arnold Networks (KANs) called Adaptive RBF-KAN, which utilizes radial basis functions (RBFs) instead of traditional B-spline bases for improved computational efficiency. This new model introduces a broader family of RBF kernels and employs leave-one-out cross-validation (LOOCV) for data-driven initialization of kernel shape parameters. Evaluations on benchmark functions demonstrate that adaptive kernel selection and shape parameters significantly improve RBF-KAN performance, with different kernels showing advantages for various data characteristics like smoothness or discontinuities.
