VARIABLE KERNEL DENSITY ESTIMATES AND VARIABLE KERNEL DENSITY ESTIMATES
Australian Journal of Statistics, 1990SummaryThe term “variable kernel density estimate” is sometimes used to mean a kernel density estimate employing a different bandwidth for each data point, and sometimes to denote a kernel density estimate with bandwidth a function of estimation location.

Generalized Kernel Density Estimator
Theory of Probability & Its Applications, 2000Summary: We introduce a new class of nonparametric density estimators. It includes the classical kernel density estimators as well as the popular Abramson's estimator. We show that the generalized estimators may perform much better than the classical one if the distribution has a heavy tail.

Choice of Kernel Function for Density Estimation
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1980Let l=f^n(x) be the kernel estimate of a density f(x) from a sample of size n. Wahba [6] has developed an upper bound to E[f(x)-l=f^n(x)]2. In the present paper, we find the kernel function of finite support [m=-T, T] that minimizes Wahba's upper bound. It is Q(y) = (1 + am=-1) (2T)m=-1 [1-m=-a|y|a] where a = 2-pm=-1, p m=ge 1.

Bootstrapping kernel spectral density estimates with kernel bandwidth estimation
2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2004We 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.

Online Discriminative Kernel Density Estimation
2010 20th International Conference on Pattern Recognition, 2010We propose a new method for online estimation of probabilistic discriminative models. The method is based on the recently proposed online Kernel Density Estimation (oKDE) framework which produces Gaussian mixture models and allows adaptation using only a single data point at a time.

On Consistency of a Kernel Estimate of a Density Function
Calcutta Statistical Association Bulletin, 1984Given a sequence of i. i. d. random variables the Lr( r⩾ 1) convergence of kernel type estimators of their common density function is studied. Also, strong consistency of the estimators is considered in the case when the random variables form a stationary sequence not necessarily i. i. d.

Kernel density estimation in adaptive tracking
2008 47th IEEE Conference on Decision and Control, 2008We investigate the asymptotic properties of a recursive kernel density estimator associated with the driven noise of multivariate ARMAX models in adaptive tracking. We establish an almost sure pointwise and uniform strong law of large numbers as well as a pointwise and multivariate central limit theorem.

In this chapter, we get our first taste of real analysis, starting with some results on the approximations of functions in L 1. The literature on this is vast, and a lot of it is ancient. The problem is that f cannot be approximated in L 1 by μ n , the empirical measure, as the total variation distance between any density f and any atomic measure (like

Kernel density estimates for sepsis classification
Computer Methods and Programs in Biomedicine, 2020Severe sepsis is a leading cause of intensive care unit (ICU) admission, length of stay, mortality, and cost. systemic inflammatory response syndrome (SIRS) and organ failure due to infection define it, but also make it hard to diagnose. Early diagnosis reduces morbidity, mortality and cost, and diagnosis is often significantly delayed due to a lack of
