RegressionGP Predict
Libraries:
Statistics and Machine Learning Toolbox /
Regression
Description
The RegressionGP Predict block predicts responses using a Gaussian process
(GP) regression object (RegressionGP
or CompactRegressionGP
).
Import a trained regression object into the block by specifying the name of a workspace variable that contains the object. The input port x receives an observation (predictor data), and the output port yfit returns a predicted response for the observation. The optional outputs ysd and yint return the standard deviation and prediction intervals of the response, respectively.
Examples
Predict Responses Using RegressionGP Predict Block
Train a Gaussian process (GP) regression model, and then use the RegressionGP Predict block for response prediction.
Ports

yint contains the 100(1 – Alpha)%
prediction
interval of the predicted response yfit for the predictor data
x. The Alpha
value is the probability that
the prediction interval does not contain the true response value for
x. The first column of yint contains the
lower limits of the prediction intervals, and the second column contains the upper
limits.

Parameters
Main
Select trained machine learning model — Gaussian process regression model
gpMdl
(default) | RegressionGP
| CompactRegressionGP
Specify the name of a workspace variable that contains a RegressionGP
object or CompactRegressionGP
object.
When you train the model by using fitrgp
, the following restriction applies:
The predictor data cannot include categorical predictors (
logical
,categorical

,string
, orcell
). If you supply training data in a table, the predictors must be numeric (double
orsingle
). Also, you cannot use theCategoricalPredictors
name-value argument. To include categorical predictors in a model, preprocess them by usingdummyvar
before fitting the model.

Alternative Functionality
You can use a MATLAB Function block with the predict
object function of a Gaussian process regression object (RegressionGP
or CompactRegressionGP
). For an example, see Predict Class Labels Using MATLAB Function Block.
When deciding whether to use the RegressionGP Predict block in the
Statistics and Machine Learning Toolbox™ library or a MATLAB Function block with the predict
function, consider the
following:
If you use the Statistics and Machine Learning Toolbox library block, you can use the Fixed-Point Tool (Fixed-Point Designer) to convert a floating-point model to fixed point.
Support for variable-size arrays must be enabled for a MATLAB Function block with the
predict
function.If you use a MATLAB Function block, you can use MATLAB functions for preprocessing or post-processing before or after predictions in the same MATLAB Function block.
