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

open access: yesAAAI Conference on Artificial Intelligence, 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 ...

Point Cloud Registration Based on MCMC-SA ICP Algorithm

open access: yesIEEE Access, 2019
Point cloud registration is very important for workpiece positioning and error evaluation. Generally, the Iterative Closest Points (ICP) algorithm is always adopted as the first choice in fine registration, but requires a more appropriate initial ...

Quantum annealing enhanced Markov-Chain Monte Carlo [PDF]

open access: yesScientific Reports
In this study, we propose quantum annealing-enhanced Markov Chain Monte Carlo (QAEMCMC), where QA is integrated into the MCMC subroutine. QA efficiently explores low-energy configurations and overcomes local minima, enabling the generation of proposal ...

On Estimation of P(Y < X) for Generalized Inverted Exponential Distribution Based on Hybrid Censored Data

open access: yesStatistica, 2021
Based on the hybrid censored samples, this article deals with the problem of point and interval estimation of the stress-strength reliability R = P(Y < X) when X and Y both have independent generalized inverted exponential distributions with different ...

Estimation of Cumulative Incidence Function in the Presence of Middle Censoring Using Improper Gompertz Distribution

open access: yesStatistica, 2021
In this paper we deal with the modelling of cumulative incidence function using improper Gompertz distribution based on middle censored competing risks survival data. Together with the unknown parameters, cumulative incidence function also estimated.

Multilevel Delayed Acceptance MCMC [PDF]

open access: yesSIAM/ASA J. Uncertain. Quantification, 2022
We develop a novel Markov chain Monte Carlo (MCMC) method that exploits a hierarchy of models of increasing complexity to efficiently generate samples from an unnormalized target distribution.

Unbiased Multilevel Monte Carlo methods for intractable distributions: MLMC meets MCMC [PDF]

open access: yesJournal of machine learning research, 2022
Constructing unbiased estimators from Markov chain Monte Carlo (MCMC) outputs is a difficult problem that has recently received a lot of attention in the statistics and machine learning communities. However, the current unbiased MCMC framework only works

Parameter estimation for X-ray scattering analysis with Hamiltonian Markov Chain Monte Carlo

open access: yesJournal of Synchrotron Radiation, 2022
Bayesian-inference-based approaches, in particular the random-walk Markov Chain Monte Carlo (MCMC) method, have received much attention recently for X-ray scattering analysis.

Neural Langevin Dynamical Sampling

open access: yesIEEE Access, 2020
Sampling technique is one of the asymptotically unbiased estimation approaches for inference in Bayesian probabilistic models. Markov chain Monte Carlo (MCMC) is a kind of sampling methods, which is widely used in the inference of complex probabilistic ...
