We study both the standard random Fourier features method for which we improve the existing bounds on the number of features required to guarantee the corresponding minimax risk convergence rate of kernel ridge regression, as well as a data-dependent modification which samples features proportional to \emph{ridge leverage scores} and further reduces the required number of features. Another line of work considers data-dependent algorithms, which use the training data to guide the generation of random Fourier features by using, e.g., kernel alignment [Sinha and Duchi2016], feature compression [Agrawal et al.2019], or the ridge leverage function [Avron et al.2017, Sun, Gilbert, and Tewari2018, Li et al.2019, Fanuel, Schreurs, and Suykens2019].

The Fourier transform, a special case of the Laplace transform, is a fundamental tool for the analysis of stationary signals. at those points is a Dirac delta function, not a finite coefficient, so the example is *still* wrong even in that generalised sense. 1 $\begingroup$ Let's say we have discrete-time stationary random signals with Gaussian PDF of mean value 0 and variance 1, whose individual signal values are uncorrelated.

Geometric Aspects of Functional Analysis, pages 84--106, 1988. R is continuous and bounded with respect to vand x, i.e., there exists a constant z. The principle can be further generalized by considering the class of kernel functions which can be decomposed as k(x;y) = Z V 06/24/2018 ∙ by Zhu Li, et al. Kernel functions define a convenient way for calculating an inner product between the data samples without explicitly lifting the data samples to the higher dimensional space. As ridge leverage scores are expensive to compute, we devise a simple approximation scheme which provably reduces the computational cost without loss of statistical efficiency. Note: T can be discrete in which case we have a discrete time series, or it could be continuous in the case of continuous time series.Sometimes, we refer to one observation of the time series {Xt} as a realisation of the series..
