Elastic impedance inversion method based on Quantum Annealing MH algorithm [PDF]

open access: yesE3S Web of Conferences, 2022
Seismic inversion is one of the important methods to realize reservoir prediction in oil and gas field exploration. The seismic stochastic inversion based on Metropolis-Hastings algorithm makes full use of well logging data and improves the vertical ...

Convergence Rates for the Constrained Sampling via Langevin Monte Carlo

open access: yesEntropy, 2023
Sampling from constrained distributions has posed significant challenges in terms of algorithmic design and non-asymptotic analysis, which are frequently encountered in statistical and machine-learning models.

Locally Scaled and Stochastic Volatility Metropolis– Hastings Algorithms

open access: yesAlgorithms, 2021
Markov chain Monte Carlo (MCMC) techniques are usually used to infer model parameters when closed-form inference is not feasible, with one of the simplest MCMC methods being the random walk Metropolis–Hastings (MH) algorithm.

DYNAMIC PROBABILITY SELECTION FOR FLOWER POLLINATION ALGORITHM BASED ON METROPOLISHASTINGS CRITERIA

open access: yesJournal of ICT, 2020
Flower Pollination Algorithm (FPA) is a relatively new meta-heuristic algorithm that adopts its metaphor from the proliferation role of flowers in plants. Having only one parameter control (i.e.

Bayesian estimation of generalized partition of unity copulas

open access: yesDependence Modeling, 2020
This paper proposes a Bayesian estimation algorithm to estimate Generalized Partition of Unity Copulas (GPUC), a class of nonparametric copulas recently introduced by [18].

Majorize–Minimize Adapted Metropolis–Hastings Algorithm

open access: yesIEEE Transactions on Signal Processing, 2020
The dimension and the complexity of inference problems have dramatically increased in statistical signal processing. It thus becomes mandatory to design improved proposal schemes in Metropolis-Hastings algorithms, providing large proposal transitions ...
