Detailed Description

Reads data in the form as it is often found in standard data sets: Raw data either just a matrix of doubles with each row a feature vector, or rows containing feature vectors and an id as last element of the row.

This functor needs the number of dimensions, the existence of ids and the filename as parameters. The according data from that file is returned by the apply method.

	ids	ids of the feature vectors

Returns:

true if apply successful or false otherwise.

bool lti::uciDataReader::apply

(

fmatrix &

data

)

const

Reads data from the file given in the parameters.

Parameters:

data

the feature vectors

Returns:

true if apply successful or false otherwise.

bool lti::uciDataReader::apply	(	dmatrix &	data,
		ivector &	ids
	)			const

Reads data and ids from the file given in the parameters.

If hasIds is false ids is empty.

Parameters:

	data	the feature vectors
	ids	ids of the feature vectors

Returns:

true if apply successful or false otherwise.

bool lti::uciDataReader::apply

(

dmatrix &

data

)

const

Reads data from the file given in the parameters.

Parameters:

data

the feature vectors

Returns:

true if apply successful or false otherwise.

virtual functor* lti::uciDataReader::clone

(

)

const [virtual]

returns a pointer to a clone of this functor.

Implements lti::functor.

uciDataReader& lti::uciDataReader::copy

(
