Contingent kernel density estimation. [PDF]

open access: yesPLoS ONE, 2012
Kernel density estimation is a widely used method for estimating a distribution based on a sample of points drawn from that distribution. Generally, in practice some form of error contaminates the sample of observed points.

Functional Kernel Density Estimation: Point and Fourier Approaches to Time Series Anomaly Detection [PDF]

open access: yesEntropy, 2020
We present an unsupervised method to detect anomalous time series among a collection of time series. To do so, we extend traditional Kernel Density Estimation for estimating probability distributions in Euclidean space to Hilbert spaces.

Multivariate kernel density estimation with a parametric support [PDF]

open access: yesOpuscula Mathematica, 2009
We consider kernel density estimation in the multivariate case, focusing on the use of some elements of parametric estimation. We present a two-step method, based on a modification of the EM algorithm and the generalized kernel density estimator, and ...

Curve fitting of the corporate recovery rates: the comparison of Beta distribution estimation and kernel density estimation. [PDF]

open access: yesPLoS ONE, 2013
Recovery rate is essential to the estimation of the portfolio's loss and economic capital. Neglecting the randomness of the distribution of recovery rate may underestimate the risk.

DEMANDE: Density Matrix Neural Density Estimation

open access: yesIEEE Access, 2023
Density estimation is a fundamental task in statistics and machine learning that aims to estimate, from a set of samples, the probability density function of the distribution that generated them.

An Improved Model for Kernel Density Estimation Based on Quadtree and Quasi-Interpolation

open access: yesMathematics, 2022
There are three main problems for classical kernel density estimation in its application: boundary problem, over-smoothing problem of high (low)-density region and low-efficiency problem of large samples.

Kernel Density Estimation Based Gaussian and Non-Gaussian Random Vibration Data Induction for High-Speed Train Equipment

open access: yesIEEE Access, 2020
Because general statistics tolerance is not applicable to the induction of non-Gaussian vibration data and the methods for converting non-Gaussian data into Gaussian data are not always effective and can increase the estimation error, a novel kernel ...

Kernel Density Derivative Estimation of Euler Solutions

open access: yesApplied Sciences, 2023
Conventional Euler deconvolution is widely used for interpreting profile, grid, and ungridded potential field data. The Tensor Euler deconvolution applies additional constraints to the Euler solution using all gravity vectors and the full gravity ...

An Assessment of Hermite Function Based Approximations of Mutual Information Applied to Independent Component Analysis

open access: yesEntropy, 2008
At the heart of many ICA techniques is a nonparametric estimate of an information measure, usually via nonparametric density estimation, for example, kernel density estimation.
