Gaussian process regression models (kriging) Gaussian process regression (GPR) models are nonparametric, kernel-based probabilistic models. To train a GPR model interactively, use theRegression Learnerapp. For greater flexibility, train a GPR model using thefitrgpfunction at the command line. After tra...
Gaussian process regression (GPR) models are nonparametric kernel-based probabilistic models. You can train a GPR model using the fitrgp function. Consider the training set {(xi,yi);i=1,2,...,n}, where xi∈ℝd and yi∈ℝ, drawn from an unknown distribution. A GPR model addresses the...

Mdl = fitrgp(Tbl,ResponseVarName) returns a Gaussian process regression (GPR) model trained using the sample data in Tbl, where ResponseVarName is the name of the response variable in Tbl. example Mdl = fitrgp(Tbl,formula) returns a Gaussian process regression (GPR) model, trained using the...
高斯随机回归在统计上是参数模型 (parametric models)。 首先,参数模型和非参数模型的区别在于模型中的参数量是否随数据的增大而增大,或者说模型的参数是有限个还是无限个(finite or infinite). 线性模型的参数仅在于线性部分,而GPR的参数在于线性部分和kernel部分,并且kernel部分是模型的重点; ...

Therefore, a novel probabilistic wind power forecasting method is proposed based on selective ensemble of finite mixture Gaussian process regression models (SEFMGPR). First, a set of diverse local Gaussian process regression (GPR) models are constructed through multimodal perturbation mechanism, i.e.,...
其实高斯过程回归 Gaussian Process Regression 就是高斯过程+贝叶斯回归。 高斯过程回归建模的主要思想是: 将基本目标函数建模为函数分布的一个样本,这个分布具有先验形式,并在加入函数观测值后更新为后验分布。这就类似于利用机器学习领域的训练数据来更新模型参数。但是与机器学习算法不一样的是,高斯过程回归是一种非...
GPs differ from standard regression models in that they define priors for entire nonlinear functions, instead of their parameters. While nonlinear effects can be incorporated into standard linear models by extending the basis functions e.g. with higher order polynomials, GPs can automatically detect an...
