Local Optimisation of Nyström Samples Through Stochastic Gradient Descent
Chapter
Full-text available
  • Mar 2023
We study a relaxed version of the column-sampling problem for the Nyström approximation of kernel matrices, where approximations are defined from multisets of landmark points in the ambient space; such multisets are referred to as Nyström samples. We consider an unweighted variation of the radial squared-kernel discrepancy (SKD) criterion as a surr...
