WebThis paper consists of evaluating the performance of a vibro-acoustic model in the presence of uncertainties in the geometric and material parameters of the model using Monte Carlo simulations (MCS). The purpose of using a meta-model is to reduce the computational cost of finite element simulations. Uncertainty analysis requires a large sample of MCS to … Web1) Non parametric regression to predict petrophysical properties from log data 2) Kriging, Sequential gaussian simulation and Bayesian updation to include secondary data in constructing subsurface realisations Computational work includes 1) Tested an Eikonal equation formulation of the diffusivity equation on pore networks.

Web高斯过程（Gaussian Process, GP）是随机过程之一，是一系列符合正态分布的随机变量在一指数集（index set）内的集合 我认为该解释中的“指数”可以理解为“维度“，按照机器学习的角度，各个指数上的随机变量可以对应地理解为各个维度上的特征。 对于一个高斯过程： X \sim N (\mu, \Sigma) 设随机变量 X = [x_1, x_2, x_3, ..., x_n]^T ，其中 n 对应上文中的维 …
