Detailed Description

This class implements the plus l - take away r algorithm descripted in: P.

Pudil, F.J. Ferri, J. Novovicova, J. Kittler. "Floating Search Methods for Feature Selection with nonmonotonic criterion functions" Proceddings of the IEEE Intl. Conf. on Pattern Recognition, 279-283, 1994; In each iteration it adds the l best features and from the source data to the destination data. Then the r least significant features are deleted from this data set. This is done until the predetermined number of features is reached As criterion function cross validation is used.

Member Function Documentation

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

extracts the k, that is a parameter, best features of src and 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.

Implements lti::featureSelector.
