New Bandwidth Selection for Kernel Quantile Estimators [PDF]

open access: yesJournal of Probability and Statistics, 2012
We propose a cross-validation method suitable for smoothing of kernel quantile estimators. In particular, our proposed method selects the bandwidth parameter, which is known to play a crucial role in kernel smoothing, based on unbiased estimation of a ...

One Value of Smoothing Parameter vs Interval of Smoothing Parameter Values in Kernel Density Estimation

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2017
Ad hoc methods in the choice of smoothing parameter in kernel density estimation, al­though often used in practice due to their simplicity and hence the calculated efficiency, are char­acterized by quite big error.

Spatial Smoothing Effect on Group-Level Functional Connectivity during Resting and Task-Based fMRI

open access: yesSensors, 2023
Spatial smoothing is a preprocessing step applied to neuroimaging data to enhance data quality by reducing noise and artifacts. However, selecting an appropriate smoothing kernel size can be challenging as it can lead to undesired alterations in final ...

The Gasser-Müller estimator

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2004
Kernel smoothing provides a simple way for finding structure in data. The idea of the kernel smoothing can be applied to a simple fixed design regression model and a random design regression model.

Maximum Entropy Approach to Massive Graph Spectrum Learning with Applications

open access: yesAlgorithms, 2022
We propose an alternative maximum entropy approach to learning the spectra of massive graphs. In contrast to state-of-the-art Lanczos algorithm for spectral density estimation and applications thereof, our approach does not require kernel smoothing.

Kernel smoothing dos dados de chuva no Nordeste [PDF]

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2014
O regime de chuvas sobre o Nordeste do Brasil é bastante complexo, sendo considerado sazonal, além de sofrer fortes influências dos fenômenos El Niño, La Niña e outros sistemas meteorológicos, como o dipolo, atuantes sobre as bacias do oceano Atlântico ...

Gaussian kernel smoothing

open access: yesCoRR, 2020
Image acquisition and segmentation are likely to introduce noise. Further image processing such as image registration and parameterization can introduce additional noise. It is thus imperative to reduce noise measurements and boost signal. In order to increase the signal-to-noise ratio (SNR) and smoothness of data required for the subsequent random ...
