Gaussian process regression models (kriging)Gaussian process regression (GPR) models are nonparametric, kernel-based probabilistic models. To train a GPR model interactively, use the Regression Learner app. For
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 , where and , drawn from an unknown distribution. A GPR model addresses the question of predicting the value of a response ...
To integrate the prediction of a Gaussian process regression model into Simulink®, you can use theRegressionGP Predictblock in the Statistics and Machine Learning Toolbox™ library or a MATLAB®Function block with thepredictfunction. For examples, seePredict Responses Using RegressionGP Predict ...
This MATLAB function returns the mean squared error for the Gaussian process regression (GPR) model gprMdl, using the predictors in Xnew and observed response in Ynew.

Train a Gaussian kernel regression model for a tall array, then calculate the resubstitution mean squared error and epsilon-insensitive error. When you perform calculations on tall arrays, MATLAB® uses either a parallel pool (default if you have Parallel Computing Toolbox™) or the local MATL...
Hence, a good model should have low values of both of the above metrics. 2.1. Gaussian process regression This section gives an overview of Gaussian process regression. For simplicity, our presentation assumes the inputs and outputs are scalar, since we only consider 1-D capacity vs. cycle ...
在实现多变量数据预测过程中,发现利用MATLAB自带的高斯过程回归(Gaussian process regression,GPR)无法实现多输入多输出的数据预测,于是利用了gpml-matlab-v4.1-2017-10-19这个工具箱,并简单实现了多变量数据的预测值以及给出了每个预测值对应的方差。 注:涉及的训练数据和测试数据会在附件中给出。
