◆ get_labels()

void MultiLabelData::get_labels	(	label_id_t	id,
		Eigen::Ref< BinaryLabelVector >	target
	)		const

overridevirtual

Gets the label vector (encoded as dense vector with elements from {-1, 1}) for the id'th class. The weights will be put into the given target buffer. Throws std::out_of_bounds, if id is not in [0, num_labels()).

Implements dismec::DatasetBase.
