Detailed Description

Computes the average recognition rate of a given subset of features from a data set.

A cross validation is performed on the given subset of features. The average recognition rate of the used classifier, is returned as the value of this cost function.

Member Function Documentation

virtual bool lti::recognitionRateOfSubset::apply	(	const std::list< int > &	in,
		double &	value
	)			[virtual]

computes the average recognition rate of the given feature subset using cross validation

Parameters:

	in	std::list with the features that are included in this test.
	value	the resulting average recognition rate

Returns:

true if apply successful or false otherwise.

Implements lti::costFunction.

virtual functor* lti::recognitionRateOfSubset::clone

(

)

const [virtual]

returns a pointer to a clone of this functor.

Implements lti::functor.

recognitionRateOfSubset& lti::recognitionRateOfSubset::copy

(

const recognitionRateOfSubset &

other

)

copy data of "other" functor.

Parameters:

other

the functor to be copied

Returns:

a reference to this functor object

Reimplemented from lti::costFunction.

const parameters& lti::recognitionRateOfSubset::getParameters

(

)

const

returns used parameters

Reimplemented from lti::functor.

virtual const char* lti::recognitionRateOfSubset::getTypeName

(

)

const [virtual]

returns the name of this type ("recognitionRateOfSubset")

Reimplemented from lti::costFunction.

recognitionRateOfSubset& lti::recognitionRateOfSubset::operator=

(

const recognitionRateOfSubset &

other

)

alias for copy member

Parameters:

other

the functor to be copied

Returns:

a reference to this functor object

Reimplemented from lti::costFunction.

virtual void lti::recognitionRateOfSubset::setSrc	(	const dmatrix &	src,
		const ivector &	srcIds
	)			[virtual]

Set the src data, that is used in applies.

This must be done before you call one of the apply methods. Later each feature can be adressed by its column number.

Reimplemented from lti::costFunction.
