CompactClassificationGAM
A CompactClassificationGAM
object is a compact version of a
Generalized Additive Model, ClassificationGAM
.
The CompactClassificationDiscriminant
does not include the training
data resulting to a smaller classifier size, which can be used for making
predictions from new data, but not for tasks such as cross validation. It
can only be created from a ClassificationDiscriminant
model by using
the compact
object method.
The available methods for a CompactClassificationGAM
object
are:
predict
savemodel

Source Code: CompactClassificationGAM
predict
'IncludeInteractions'
, includeInteractions)Predict labels for new data using the Generalized Additive Model (GAM) stored in a CompactClassificationGAM object.
label = predict (obj, XC)
returns the predicted
labels for the data in XC based on the model stored in the
CompactClassificationGAM object, obj.
label = predict (obj, XC, 'IncludeInteractions',
includeInteractions)
allows you to specify whether interaction
terms should be included when making predictions.
[label, score] = predict (…)
also returns
score, which contains the predicted class scores or posterior
probabilities for each observation.

class object.

savemodel
Save a ClassificationGAM object.
savemodel (obj, filename)
saves each property of a
CompactClassificationGAM object into an Octave binary file, the name
of which is specified in filename, along with an extra variable,
which defines the type classification object these variables constitute.
Use loadmodel
in order to load a classification object into
Octave’s workspace.
