lti::uciDataWriter Class Reference

Writes 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, or raw data with or without ids and a header with the number of points and the dimensionality.

Detailed Description

Writes 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, or raw data with or without ids and a header with the number of points and the dimensionality.

With parameter append it can be choosen if the data if appended to an existing file or if the file should be new created.

If the filename exists and append is false, your data will be lost.

This functor needs the filename and the existence of a header as parameters. With the third parameter you can choose if the data should be appended of if a new file will be created.

Member Function Documentation

bool lti::uciDataWriter::apply	(	std::list< dmatrix > &	data,
		ivector &	ids
	)			const

Writes data and ids to the file given in the parameters.

The i-th element of ids is the number to which the points in the i-th matrix in data belong to

Parameters:

	data	the feature vectors
	ids	IDs for the elements in data.

Returns:

true if apply successful or false otherwise.

bool lti::uciDataWriter::apply

(

std::list< dmatrix > &

data

)

const

Writes data and ids to the file given in the parameters.

It is suggested that each element of the list is one Cluster

Parameters:

data

the feature vectors

Returns:

true if apply successful or false otherwise.

bool lti::uciDataWriter::apply	(	fmatrix &	data,
		ivector &	ids
	)			const

Writes data and ids to the file given in the parameters.

Parameters:

	data	the feature vectors
	ids	ids of the feature vectors

Returns:

true if apply successful or false otherwise.

bool lti::uciDataWriter::apply

(

fmatrix &

data

)

const

Writes data to the file given in the parameters.

Parameters:

data

the feature vectors

Returns:

true if apply successful or false otherwise.

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

Writes data and ids to the file given in the parameters.

Parameters:

	data	the feature vectors
	ids	ids of the feature vectors

Returns:

true if apply successful or false otherwise.

bool lti::uciDataWriter::apply

(

dmatrix &

data

)

const

Writes data to the file given in the parameters.

Parameters:

data
