Abstract:
This article considers weighted approximation of multivariate function inreproducing kernel Hilbert space, and gives a relation between nth minimal errors forstandard and linear information in the randomized setting. Using this relation we canestimate the nth minimal error for standard information by the nth minimal errorfor linear information, and study the tractability and strong tractability for these twoclasses of information.
