The Convergence Rate for a K-Functional in Learning Theory

It is known that in the field of learning theory based on reproducing kernel Hilbert spaces the upper bounds estimate for a K-functional is needed. In the present paper, the upper bounds for the K-functional on the unit sphere are estimated with spherical harmonics approximation. The results show that convergence rate of the K-functional depends upon the smoothness of both the approximated func...

Convergence rate examples and theory

If you use lfe for various tasks, you will notice that some estimations converge fast, whereas others converge slowly. Convergence rate of the methods used by lfe is not a walk in the park. Here are some examples.

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

On the Rate of Convergence of the Functional k-NN Estimates

Let F be a general separable metric space and denote by Dn = {(X1, Y1), . . . , (Xn, Yn)} independent and identically distributed F × R-valued random variables with the same distribution as a generic pair (X, Y ). In the regression function estimation problem, the goal is to estimate, for fixed x ∈ F , the regression function r(x) = E[Y |X = x] using the data Dn. Motivated by a broad range of p...
