Member Function Documentation

virtual dmatrix lti::featureSelector::apply	(	const dmatrix &	src,
		const ivector &	srcIds
	)			const [virtual]

Extracts the best features of src copies them to dest.

Parameters:

	src	dmatrix with the source data.
	srcIds	ivector with the ids corresponding to src

Returns:

the data set, that contains only the extracted features

virtual bool lti::featureSelector::apply	(	const dmatrix &	src,
		const ivector &	srcIds,
		dmatrix &	dest
	)			const [pure virtual]

Extracts the best features of src copies them to dest.

Parameters:

	src	dmatrix with the source data.
	srcIds	ivector with the ids corresponding to src
	dest	dmatrix where the result will be left.

Returns:

true if apply successful or false otherwise.

Implemented in lti::plusLTakeAwayR, and lti::sffs.

virtual functor* lti::featureSelector::clone

(

)

const [pure virtual]

returns a pointer to a clone of this functor.
