Learning between the peaks: sharp asymptotics for kernel ridge regression under power-law anisotropy
Publisher summary· verbatim
arXiv:2608.28564v1 Announce Type: cross Abstract: We study kernel ridge regression under anisotropic Gaussian data, where the input covariance decays as a power law with exponent $\alpha\geq 0$ for polynomial inner-product kernels. We derive asymptotically sharp expressions for the kernel spectrum a
