Function Documentation

int OpenANN::FANN::load	(	Eigen::MatrixXd &	in,
		Eigen::MatrixXd &	out,
		const char *	filename
	)

Read a FANN-encoded dataset from the filesystem and load its values into given in- and output matrices.

Parameters

in	input matrix with an unspecific dimension that will contain the data
out	output matrix with an unspecific dimension that will contain the data.
filename	name to the corresponding libsvm dataset file

Returns

the number of loaded instances from the dataset

int OpenANN::FANN::load	(	Eigen::MatrixXd &	in,
		Eigen::MatrixXd &	out,
		std::istream &	stream
	)

Read a FANN-encoded dataset from any input stream and load its values into given in- and output matrices.

Parameters

in	input matrix with an unspecific dimension that will contain the data
out	output matrix with an unspecific dimension that will contain the data.
stream	general STL data stream for getting libsvm-encoded datasets

Returns

the number of loaded instances from the dataset

void OpenANN::FANN::save	(	const Eigen::MatrixXd &	in,
		const Eigen::MatrixXd &	out,
		const char *	filename
	)

Export a given dataset represented by in- and output matrices into a libsvm file.

Parameters

in	matrix containing all input values (features)
out	matrix containt all output values (classes, targets)
filename	name to the generating libsvm dataset file

void OpenANN::FANN::save	(	const Eigen::MatrixXd &	in,
		const Eigen::MatrixXd &	out,
		std::ostream &	stream
	)

Write a given dataset from in- and output matrices to an output stream in libsvm format.

Parameters

in	matrix containing all input values (features)
out	matrix containt all output values (classes, targets)
stream	general STL data stream that will receive libsvm encoded dataset
