نویسندگان
چکیده
The problem of finding the pattern that deviates from other observation is termed as outlier. detection outlier getting importance in research area nowadays due to reason technique has been used various mission critical applications such military, health care, fault recovery, and many. analysis functional data its depth function plays a crucial role statistical model for detecting values alone not enough outliers, since all low be an main using classical it cannot cop up with high dimensionality This paper proposed novel based on Reproducing Kernel Hilbert Space curve (RKHS) outliers data. RKHS special space associated kernel so reproduces each enhance performance function. method uses distance weighted discrimination classification avoids overfitting provides better generalizability dimensions. depths perform performances number artificial real sets.

Reproducing Kernel Space Hilbert Method for Solving Generalized Burgers Equation
In this paper, we present a new method for solving Reproducing Kernel Space (RKS) theory, and iterative algorithm for solving Generalized Burgers Equation (GBE) is presented. The analytical solution is shown in a series in a RKS, and the approximate solution u(x,t) is constructed by truncating the series. The convergence of u(x,t) to the analytical solution is also proved.
متن کاملA Reproducing Kernel Hilbert Space Approach to Functional Linear Regression
We study a smoothness regularization method for functional linear regression and provide a unified treatment for both the prediction and estimation problems. By developing a tool on simultaneous diagonalization of two positive definite kernels, we obtain shaper results on the minimax rates of convergence and show that smoothness regularized estimators achieve the optimal rates of convergence fo...
متن کاملVoice activity detection in a reguarized reproducing kernel hilbert space
Voice activity detection (VAD) is used to detect whether the acoustic signal belongs to speech or non-speech clusters based on the statistical distribution of the acoustic features. Traditional VAD algorithms are applied in a linear transformed space without any constraint relating to the special characteristics speech or noise. As a result, the VAD algorithms are not robust to noise interferen...
متن کاملReproducing Kernel Hilbert Space vs. Frame Estimates
We consider conditions on a given system F of vectors in Hilbert space H, forming a frame, which turn H into a reproducing kernel Hilbert space. It is assumed that the vectors in F are functions on some set Ω. We then identify conditions on these functions which automatically give H the structure of a reproducing kernel Hilbert space of functions on Ω. We further give an explicit formula for th...
متن کاملSubspace Regression in Reproducing Kernel Hilbert Space
We focus on three methods for finding a suitable subspace for regression in a reproducing kernel Hilbert space: kernel principal component analysis, kernel partial least squares and kernel canonical correlation analysis and we demonstrate how this fits within a more general context of subspace regression. For the kernel partial least squares case a least squares support vector machine style der...
