Detailed Description

This class implements the sequential forward search algorithm for feature selection.

It is based on the PlusRTakeAwayR Algorithm with parameters r=0 and l=1. It starts with an empty destination matrix. Each iteration inserts the most significant feature from the source data set into the destination until the predetermined number of features is reached.

Member Function Documentation

bool lti::sequentialForwardSearch::apply	(	const dmatrix &	src,
		const ivector &	srcIds,
		dmatrix &	dest
	)

copy the nbFeatures best features to the dest matrix

Parameters:

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

Returns:

true if apply successful or false otherwise.
