Hi,

I know that a for a Mercer kernel I have :

$\displaystyle k(x,y) = \int_{-\infty}^{\infty} [\Phi(x)]_\lambda^* [\Phi(y)]_\lambda d\lambda = < [\Phi(x)]_\lambda, [\Phi(y)]_\lambda> $

how is $\displaystyle [\Phi(x)]_\lambda $ related to the eigenfunctions of the kernel ?

I'm not very familiar with these concepts so please be patient

Alexis
