Create compact regression ensemble
cens = compact(ens)
a compact version of
cens = compact(
ens. You can predict regressions
cens exactly as you can using
cens does not contain training data,
you cannot perform some actions, such as cross validation.
A regression ensemble created with
A compact regression ensemble.
Compare the size of a regression ensemble for the
carsmall data to the size of the compact version of the ensemble.
carsmall data set and select acceleration, number of cylinders, displacement, horsepower, and vehicle weight as predictors.
load carsmall X = [Acceleration Cylinders Displacement Horsepower Weight];
Train an ensemble of regression trees.
ens = fitrensemble(X,MPG);
Create a compact version of
ens and compare ensemble sizes.
cens = compact(ens); b = whos('ens'); c = whos('cens'); [b.bytes c.bytes] % b.bytes = size of ens and c.bytes = size of cens
ans = 1×2 493838 461479
The compact ensemble uses less memory.
