CompactRegressionEnsemble
Package: classreg.learning.regr
Compact regression ensemble class
Description
Compact version of a regression ensemble (of class RegressionEnsemble
). The compact version does not include the data for
training the regression ensemble. Therefore, you cannot perform some tasks with a
compact regression ensemble, such as cross validation. Use a compact regression ensemble
for making predictions (regressions) of new data.
Construction
constructs a compact decision ensemble from a full decision ensemble.ens
=
compact(fullEns
)
Input Arguments

A regression ensemble created by 
Properties

Categorical predictor
indices, specified as a vector of positive integers. 

A character vector describing how the ensemble combines learner predictions. 

Expanded predictor names, stored as a cell array of character vectors. If the model uses encoding for categorical variables, then


Number of trained learners in the ensemble, a positive scalar. 

A cell array of names for the predictor variables, in the order in which
they appear in 

A character vector with the name of the response variable


Function handle for transforming scores, or character vector representing
a builtin transformation function. Add or change a ens.ResponseTransform = @function 

The trained learners, a cell array of compact regression models. 

A numeric vector of weights the ensemble assigns to its learners. The ensemble computes predicted response by aggregating weighted predictions from its learners.

Tips
For a compact ensemble of regression trees, the Trained

of ens
stores a cell vector of ens.NumTrained
