Member Function Documentation

float64_t * get_basealphas_ptr	(	index_t *	y,
		index_t *	x
	)

required for CMKLMulticlass constraint computation

Parameters:

	y	height of basealphas
	x	width of basealphas

Returns:

basealphas basealphas[k][j] is the alpha for class k and sample j which is untransformed compared to the alphas stored in CSVM* members

Definition at line 182 of file GMNPSVM.cpp.

virtual EClassifierType get_classifier_type

(

)

[virtual]

get classifier type

Returns:

classifier type GMNPSVM

Reimplemented from CClassifier.

Definition at line 57 of file GMNPSVM.h.

virtual const char* get_name

(

void

)

const [virtual]

Returns:

object name

Reimplemented from CSVM.

Definition at line 71 of file GMNPSVM.h.

bool train

(

CFeatures *

data = NULL

)

[virtual]

train SVM

Parameters:

data

training data (parameter can be avoided if distance or kernel-based classifiers are used and distance/kernels are initialized with train data)

Returns:

whether training was successful

Reimplemented from CClassifier.
