Title: Fixing an error in Caponnetto and de Vito (2007),
Abstract: The seminal paper of Caponnetto and de Vito (2007) provides minimax-optimal
rates for kernel ridge regression in a very general setting. Its proof,
however, contains an error in its bound on the effective dimensionality. In
this note, we explain the mistake, provide a correct bound, and show that the
main theorem remains true.
