Gaussian RBF RKHS asymptotically approaches Euclidean space, study finds

A new research paper explores the asymptotic behavior of Gaussian RBF reproducing kernel Hilbert spaces (RKHS) and their relationship to Euclidean space. The study demonstrates that in the large bandwidth limit, the Gaussian RBF RKHS becomes asymptotically isometric to Euclidean space. This convergence implies that kernel-based methods relying on RKHS metric properties will approach the results of linear kernels, a finding supported by experiments showing that a measure of data eccentricity predicts convergence behavior.

    Data eccentricity, asymptotics of Gaussian RBF reproducing kernel Hilbert space, and kernel PCA

    arXiv:2607.21823v1 Announce Type: new Abstract: We show that, up to isotropic scaling, the Gaussian RBF reproducing kernel Hilbert space (RKHS) is asymptotically isometric to Euclidean space in the large bandwidth limit. This strongly suggests that kernel-based constructions reli…
