General and Local: Averaged k-Dependence Bayesian Classifiers

open access: yesEntropy, 2015
The inference of a general Bayesian network has been shown to be an NP-hard problem, even for approximate solutions. Although k-dependence Bayesian (KDB) classifier can construct at arbitrary points (values of k) along the attribute dependence spectrum ...

Extending Hilbert–Schmidt Independence Criterion for Testing Conditional Independence

open access: yesEntropy, 2023
The Conditional Independence (CI) test is a fundamental problem in statistics. Many nonparametric CI tests have been developed, but a common challenge exists: the current methods perform poorly with a high-dimensional conditioning set.

Local dependence in bivariate copulae with Beta marginals

open access: yesRevista Colombiana de Estadística, 2017
The local dependence function (LDF) describes changes in the correlation structure of continuous bivariate random variables along their range. Bivariate density functions with Beta marginals can be used to model jointly a wide variety of data with ...

Local time dependence of polar mesospheric clouds: a model study [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
The Mesospheric Ice Microphysics And tranSport model (MIMAS) is used to study local time (LT) variations of polar mesospheric clouds (PMCs) in the Northern Hemisphere during the period from 1979 to 2013. We investigate the tidal behavior of brightness,

Magnetic local time (MLT) dependence of auroral peak emission height and morphology [PDF]

open access: yesAnnales Geophysicae, 2022
We investigate the bulk behaviour of auroral structures and peak emission height as a function of magnetic local time (MLT). These data are collected from the Fennoscandian Lapland and Svalbard latitudes from seven identical auroral all-sky cameras (ASC)

Modeling local dependence in latent vector autoregressive models.

open access: yesBiostatistics, 2019
We propose a Bayesian latent vector autoregressive (LVAR) model to analyze multivariate longitudinal data of binary and ordinal variables (items) as a function of a small number of continuous latent variables.

Multiple Imputation of Missing Categorical and Continuous Values via Bayesian Mixture Models With Local Dependence [PDF]

open access: yes, 2014
We present a nonparametric Bayesian joint model for multivariate continuous and categorical variables, with the intention of developing a flexible engine for multiple imputation of missing values. The model fuses Dirichlet process mixtures of multinomial
