Markov Chain Monte Carlo Simulation to Estimate Material Properties of a Layered Half-space
نویسندگان
چکیده
A Markov chain Monte Carlo (MCMC) simulation is proposed for probabilistic full waveform inversion (FWI) in a layered half-space. Dynamic responses on the half-space surface are estimated using thin-layer method when harmonic vertical force applied. Subsequently, posterior probability distribution function and corresponding objective formulated to minimize difference between estimations observed data as well that of model parameters from prior information. Based gradient function, proposal an acceptance MCMC samples proposed. The applied several examples. It demonstrated FWI can estimate material properties such shear-wave velocities

Markov Chain Monte Carlo
Markov chain Monte Carlo is an umbrella term for algorithms that use Markov chains to sample from a given probability distribution. This paper is a brief examination of Markov chain Monte Carlo and its usage. We begin by discussing Markov chains and the ergodicity, convergence, and reversibility thereof before proceeding to a short overview of Markov chain Monte Carlo and the use of mixing time...

This paper gives a brief introduction to Markov Chain Monte Carlo methods, which offer a general framework for calculating difficult integrals. We start with the basic theory of Markov chains and build up to a theorem that characterizes convergent chains. We then discuss the MetropolisHastings algorithm.
متن کاملMarkov chain Monte Carlo
One of the simplest and most powerful practical uses of the ergodic theory of Markov chains is in Markov chain Monte Carlo (MCMC). Suppose we wish to simulate from a probability density π (which will be called the target density) but that direct simulation is either impossible or practically infeasible (possibly due to the high dimensionality of π). This generic problem occurs in diverse scient...
