On Convergence of Kernel Learning Estimators

SIAM Journal on Optimization, 2010
The paper studies convex stochastic optimization problems in a reproducing kernel Hilbert space (RKHS). The objective (risk) functional depends on functions from this RKHS and takes the form of a mathematical expectation (integral) of a nonnegative integrand (loss function) over a probability measure.

Estimating the Variance of a Kernel Density Estimation

2010
This article proposes an interval-valued extension of kernel density estimation. We show that the imprecision of this interval-valued estimation is highly correlated with the variance of the density estimation induced by the statistical variations of the set of observations.

Bootstrapping kernel spectral density estimates with kernel bandwidth estimation

2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2004
We address the problem of confidence interval estimation of spectral densities using the bootstrap. Of special interest is the choice of the kernel global bandwidth. First, we investigate resampling based techniques for the choice of the bandwidth.

A Note on the Variable Kernel Estimate

Biometrical Journal, 1982
AbstractBy a simple example it is shown how in special cases the variable kernel estimate may not give the correct qualitative impression of the estimated density.To exclude such effects a slightly modified definition of the bandwidth of the kernels is proposed.

Kernel Estimates of Dose Response

Biometrics, 1988
A nonparametric method for analyzing quantal response data from an indirect bioassay experiment is proposed. Kernel estimates of the dose-response curve are used to develop approximate confidence intervals for (i) the optimal combination dose of a drug with therapeutic effects at low doses and toxic effects at high doses, and (ii) the lethal dose ...

Undersmoothed Kernel Entropy Estimators

IEEE Transactions on Information Theory, 2008
We develop a ldquoplug-inrdquo kernel estimator for the differential entropy that is consistent even if the kernel width tends to zero as quickly as 1/N, where N is the number of independent and identically distributed (i.i.d.) samples. Thus, accurate density estimates are not required for accurate kernel entropy estimates; in fact, it is a good idea ...

Complementary Kernel Density Estimation

Pattern Recognition Letters, 2012
Generative models for vision and pattern recognition have been overshadowed in recent years by powerful non-parametric discriminative models. These discriminative models can learn arbitrary decision boundaries between classes and have proved very effective in classification and detection problems.
