Spectral representations of interpolation spaces of reproducing kernel Hilbert spaces

Michael Bitzer, Ingo Steinwart

In statistical learning theory, interpolation spaces of the form $[L^{2}, H]_{θ, r}$ , where $H$ is a reproducing kernel Hilbert space, are in widespread use. So far, however,…

Which Spaces can be Embedded in Reproducing Kernel Hilbert Spaces?

Max SchÃ¶lpple, Ingo Steinwart

Given a Banach space $E$ consisting of functions, we ask whether there exists a reproducing kernel Hilbert space $H$ with bounded kernel such that $E \subset H$ . More generally, we…
