Deep Neural Tangent Kernel and Laplace Kernel Have the Same RKHS

Lin Chen · Sheng Xu

Keywords: [ neural tangent kernel ] [ Reproducing kernel Hilbert space ] [ Laplace kernel ] [ Singularity analysis ]


Abstract: We prove that the reproducing kernel Hilbert spaces (RKHS) of a deep neural tangent kernel and the Laplace kernel include the same set of functions, when both kernels are restricted to the sphere Sd1. Additionally, we prove that the exponential power kernel with a smaller power (making the kernel less smooth) leads to a larger RKHS, when it is restricted to the sphere Sd1 and when it is defined on the entire Rd.
