Detailed Description

Class GMNPSVM implements a one vs. rest MultiClass SVM.

It uses CGMNPLib for training (in true multiclass-SVM fashion).

Member Function Documentation

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

(

)

const [virtual]

Returns:

object name

Reimplemented from CSVM.

Definition at line 68 of file GMNPSVM.h.

void getbasealphas

(

::std::vector< ::std::vector< float64_t > > &

basealphas

)

required for CMKLMulticlass constraint computation

Parameters:

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 163 of file GMNPSVM.cpp.

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.

Definition at line 37 of file GMNPSVM.cpp.

Member Data Documentation

::std::vector< ::std::vector<float64_t> > m_basealphas [protected]

required for CMKLMulticlass stores the untransformed alphas of this algorithm whereas CSVM* members stores a transformed version of it m_basealphas[k][j] is the alpha for class k and sample j
