Orthogonal parallel MCMC methods for sampling and optimization

open access: yes, 2016
Monte Carlo (MC) methods are widely used for Bayesian inference and optimization in statistics, signal processing and machine learning. A well-known class of MC methods are Markov Chain Monte Carlo (MCMC) algorithms. In order to foster better exploration

Digital Forensics Report Management System for MCMC (DFRMS-MCMC)

open access: yes, 2023
Malaysian Communication and Multimedia Commission (MCMC) uses a physical report storage system and a stand-alone management system. Both systems have a flaw because workers must come to the office to use it. Therefore, this Digital Forensics Report Case Management System is proposed to help solving those problems.

Disputes of the senses in the ways of inhabiting the world. A conceptual proposal to (re) think the habitat in intercultural terms

open access: yesNuevo Itinerario, 2021
The article that we present here is part of a research / extension process that lasted for more than two years in the Puna and Chaco of Salta, in northern Argentina, with significant interaction with the Kolla de Hurcuro and Wichí de El peoples.

Adaptive Metropolis-coupled MCMC for BEAST 2 [PDF]

open access: yesPeerJ, 2020
With ever more complex models used to study evolutionary patterns, approaches that facilitate efficient inference under such models are needed. Metropolis-coupled Markov chain Monte Carlo (MCMC) has long been used to speed up phylogenetic analyses and to

Speeding Up MCMC by Efficient Data Subsampling

open access: yes, 2018
We propose Subsampling MCMC, a Markov Chain Monte Carlo (MCMC) framework where the likelihood function for $n$ observations is estimated from a random subset of $m$ observations.

A Classical and Bayesian Approach for Parameter Estimation in Structural Equation Models

open access: yesJournal of New Theory, 2020
Structural Equation Models (SEMs) with latent variables provide a general framework for modelling relationships in multivariate data. Although SEMs are most commonly used in studies involving intrinsically latent variables, such as happiness, quality of ...

On the Anatomy of MCMC-Based Maximum Likelihood Learning of Energy-Based Models

open access: yes, 2019
This study investigates the effects of Markov chain Monte Carlo (MCMC) sampling in unsupervised Maximum Likelihood (ML) learning. Our attention is restricted to the family of unnormalized probability densities for which the negative log density (or ...

ENHANCING VOLATILITY MODELING WITH LOG-LINEAR REALIZED GARCH-CJ: EVIDENCE FROM THE TOKYO STOCK PRICE INDEX

open access: yesBarekeng
This study compares the Log-linear Realized GARCH (LRG) and its extension with Continuous and Jump components (LRG-CJ) in modeling the volatility of financial assets, using daily data from the Tokyo Stock Price Index (TOPIX) over 2004–2011.

Bayesian Estimation of Mixed Multinomial Logit Models: Advances and Simulation-Based Evaluations

open access: yes, 2019
Variational Bayes (VB) methods have emerged as a fast and computationally-efficient alternative to Markov chain Monte Carlo (MCMC) methods for scalable Bayesian estimation of mixed multinomial logit (MMNL) models.

SpatialESD: Spatial Ensemble Domain Detection in Spatial Transcriptomics

open access: yesAdvanced Science, EarlyView.
ABSTRACT Spatial transcriptomics (ST) measures gene expression while preserving spatial context within tissues. One of the key tasks in ST analysis is spatial domain detection, which remains challenging due to the complex structure of ST data and the varying performance of individual clustering methods. To address this, we propose SpatialESD, a Spatial
