	Hilbert space - Wikipedia, the free encyclopedia
		Hilbert spaces allow simple geometric concepts, like projection and change of basis to be applied to infinite dimensional spaces, such as function spaces.
		Hilbert spaces are of crucial importance in the mathematical formulation of quantum mechanics.
		Of all the infinite-dimensional topological vector spaces, the Hilbert spaces are the most "well-behaved" and the closest to the finite-dimensional spaces.

		Hilbert spaces serve to clarify and generalize the concept of Fourier expansion and certain linear transformations such as the Fourier transform.
		Hilbert spaces are of crucial importance in the mathematical formulation of quantum mechanics, although many basic features of quantum mechanics can be understood without going into details about Hilbert spaces.
		These are function spaces associated to measure spaces (X, M, μ), where M is a σ-algebra of subsets of X and μ is a countably additive measure on M.

	Reproducing Kernel Hilbert Space (RKHS) method.
		However, in contrast to the delta function, the reproducing kernels are continuous bounded functions and can be tailored to carry physical information on the particular system or problem [26].
		Reproducing kernels can in general be constructed from any complete system of linearly independent or compact functions (e.g., orthogonal polynomials [5] and wavelets [27]).
		Smooth global multi-dimensional reproducing kernels have been successfully utilized in other contexts for multivariate interpolation (e.g., in computer aided geometric design [28, 29]) and to solve differential equations by collocation [30].

		One of the high points of this paper is introduction of reproducing kernel Hilbert spaces as a tool for the analysis of time series.
		The main motivation for introduction of reproducing kernel Hilbert spaces is to give a canonical map from time series to Hilbert spaces.
		Parzen also shows how to relate reproducing kernel Hilbert spaces to Karhunen-Loeve theorems, which are simply tools to write down the Hilbert space in a particular basis.

		By using an appealing parameterization and projection techniques in a reproducing kernel Hilbert space, recursions for the effective parameters and a sparse gaussian approximation of the posterior process are obtained.
		We describe the spectral representation of the various classes of kernels and conclude with a discussion on the characterization of nonlinear maps that reduce nonstationary kernels to either stationarity or local stationarity.
		We derive novel analytic expressions for the predictive mean and variance for Gaussian kernel shapes under the assumption of a Gaussian input distribution in the static case, and of a recursive Gaussian predictive density in iterative forecasting.

		A family of regularized least squares regression models in a Reproducing Kernel Hilbert Space is extended by the kernel partial least squares (PLS) regression model.
		PLS is useful in situations where the number of explanatory variables exceeds the number of observations and/or a high level of multicollinearity among those variables is assumed.
		We give the theoretical description of the kernel PLS algorithm and we experimentally compare the algorithm with the existing kernel PCR and kernel ridge regression techniques.

		However, the kernel is not a correct reproducing kernel, because the function for x = y becomes infinite.

		Absolute continuity means intuitively that the signal has paths which are quite smoother than those of the noise and all available evidence says that the right amount of smoothness is expressed by the requirement that the signal paths belong to the reproducing kernel Hilbert space (RKHS) of the noise.

		The functions, $k(x_{i}, \cdot)$, are known as reproducing kernels and $\mathcal{F}$ is a reproducing kernel Hilbert space (RKHS).
		Unlike iterative solutions for the more general Hilbert space setting, the proofs presented make use of the spectral representation of the kernel.

	Paper Abstract
		Kernel models for classification and regression have emerged as widely applied tools in statistics and machine learning.
		Functional analytic results ensure that such a non-parametric prior specification induces a class of functions that span the reproducing kernel Hilbert space corresponding to the selected kernel.
		The practical benefits and modelling flexibility of the Bayesian kernel framework are illustrated in both simulated and real data examples that address prediction and classification inference with high-dimensional data.

	Kernel Sliced Inverse Regression with Applications on Classification
		The kernel mixtures lead the transformed data distribution to more Gaussian like and better symmetrically distributed which provide more suitable conditions for performing SIR analysis.
		We provide a theoretical description of the kernel SIR algorithm in the framework of reproducing kernel Hilbert space (RKHS).
		The applications using kernel SIR features on the classification of microarray data and other real world data are reported along with the comparison of some existing dimension reduction techniques.

	Robotics Institute: Policy Search in Reproducing Kernel Hilbert Space
		These works may not be reposted without the explicit permission of the copyright holder.
		Policy search has numerous advantages: it does not rely on the Markov assumption, domain knowledge may be encoded in a policy, the policy may require less representational power than a value-function approximation, and stable and convergent algorithms are well-understood.
		In this work, we show how policy search (with or without the additional guidance of value-functions) in a Reproducing Kernel Hilbert Space gives a simple and rigorous extension of the technique to non-parametric settings.

	The Kernel Trick
		K(x,w) is a kernel in a reproducing kernel Hilbert space or rushed to the library or to the guy next door to find out, and probably very soon after that said aha!, K(x,w) is the kernel of a RKHS.
		The kernel function becomes useful for choosing the classification boundary but even that could be empirically approximated.
		The point is that it is obvious that a choice of kernel function is an ad-hoc way of sweeping under the rug prior information into the problem, indutransductibly (!) ducking the holy Bayes Theorem.

	Non-linear Wiener filter in reproducing kernel Hilbert space
		We introduce the non-linear Wiener filter, which is a kernel-based extension of the Wiener filter.
		When the kernel method is applied to the Wiener filter directly, the dimensions of the space where the calculation has to be done is very large since noise samples have to be used.

		At the most fundamental level, we might wish to determine whether two distributions are the same, based on samples from each - this is known as the two-sample or homogeneity problem.
		We use kernel methods to address this problem, by mapping probability distributions to elements in a reproducing kernel Hilbert space (RKHS).
		Given a sufficiently rich RKHS, these representations are unique: thus comparing feature space representations allows us to compare distributions without ambiguity.

		Abstract: Given a positive definite, bounded linear operator $A$ on the Hilbert space $\mathcal{H}_0:=l^2(E)$, we consider a reproducing kernel Hilbert space $\mathcal{H}_+$ with a reproducing kernel $A(x,y)$.
		Imposing further conditions on the operator $A$, we also consider another reproducing kernel Hilbert space $\mathcal{H}_-$ with a kernel function $B(x,y)$, which is the representation of the inverse of $A$ in a sense, so that $\mathcal{H}_-\supset\mathcal{H}_0\supset\mathcal{H}_+$ becomes a rigged Hilbert space.
