Reduce size of discriminant analysis classifier

Syntax

CMdl = compact(Mdl)

Description

CMdl = compact(Mdl) returns a CompactClassificationDiscriminant version of the trained discriminant analysis classifier Mdl.

You can predict classifications using the CompactClassificationDiscriminant object CMdl in the same way as when you use Mdl. However, because CMdl does not contain training data, you cannot perform some actions, such as cross-validation.

Examples

Compare the size of the discriminant analysis classifier for Fisher's iris data to the compact version of the classifier.

load fisheriris
fullobj = fitcdiscr(meas,species);
cobj = compact(fullobj);
b = whos('fullobj'); % b.bytes = size of fullobj
c = whos('cobj'); % c.bytes = size of cobj
[b.bytes c.bytes] % shows cobj uses 60% of the memory
ans =
       18578       11498
