Member Function Documentation

template<class Classifier , class Data >

void theplu::yat::classifier::EnsembleBuilder< Classifier, Data >::build

(

void

)

Generate ensemble.

Function trains each member of the Ensemble.

template<class Classifier , class Data >

const Classifier & theplu::yat::classifier::EnsembleBuilder< Classifier, Data >::classifier

(

size_t

i

)

const

Returns

ith classifier

template<class Classifier , class Data >

void theplu::yat::classifier::EnsembleBuilder< Classifier, Data >::predict	(	const Data &	data,
		std::vector< std::vector< statistics::Averager > > &	result
	)

Predict a dataset using the ensemble.

If data is a KernelLookup each column should correspond to a test sample and each row should correspond to a training sample. More exactly row in data should correspond to the same sample as row/column in the training kernel corresponds to.

template<class Classifier , class Data >

unsigned long theplu::yat::classifier::EnsembleBuilder< Classifier, Data >::size

(

void

)

const

Returns

Number of classifiers in ensemble. Prior build(void) is issued size is zero.

template<class Classifier , class Data >

const std::vector< std::vector< statistics::Averager > > & theplu::yat::classifier::EnsembleBuilder< Classifier, Data >::validate

(

void

)

Generate validation data for ensemble.

validate()[i][j] return averager for class i for sample j
