compact

Class: ClassificationDiscriminant

Compact discriminant analysis classifier

Syntax

cobj = compact(obj)

Description

cobj = compact(obj) creates a compact version of obj.

Input Arguments

obj

Discriminant analysis classifier created using fitcdiscr.

Output Arguments

cobj

Compact classifier. cobj has class CompactClassificationDiscriminant. You can predict classifications using cobj exactly as you can using obj. However, since cobj 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
