Kernel-Induced Sampling Theorem for A Class of Mapping-Prescribed Reproducing Kernel Hilbert Spaces Kernel-Induced Sampling Theorem for A Class of Mapping-Prescribed Reproducing Kernel Hilbert Spaces Akira, Tanaka Akira, Tanaka SIP1 A reproducing kernel is often interpreted as an inner product of two input vectors mapped into a certain space. On the contrary, if a mapping and a metric of the range space of the mapping are specified, the corresponding reproducing kernel and the unique corresponding reproducing kernel Hilbert space are automatically specified. In this paper, we introduce a class of reproducing kernel Hilbert spaces prescribed by an arbitrarily fixed mapping, and discuss properties of the spaces. Moreover, we give a necessary and sufficient condition that leads the sampling theorem (perfect reconstruction of a function from sampling points) for a reproducing kernel Hilbert space in the class. In addition, we theoretically analyze the role of a metric, by which one reproducing kernel Hilbert space among the class is specified, of the class in the function reconstruction process.
