Detailed Description

template<typename eT>
class mic::importers::CIFARImporter< eT >

Class responsible for importing CIFAR images. Returns a batch of Tensors.

Author: tkornuta

Definition at line 41 of file CIFARImporter.hpp.

Constructor & Destructor Documentation

template<typename eT >

mic::importers::CIFARImporter< eT >::CIFARImporter	(	std::string	node_name_ = `"cifar_importer"`,
		std::string	data_filename_ = `""`,
		int	min_sample_ = `-1`,
		int	max_sample_ = `-1`
	)

inline

Constructor. Sets CIFAR image default properties. Registers properties.

Parameters

node_name_	Name of the node in configuration file.
data_filename_	File(s) (with path) containing images. If data is supposed to be loaded from more than one files, they should be separated by a semicolon (;).
min_sample_	Index of first sample to be added to batch (samples < min_sample_ will be skipped) (DEFAULT=-1 - all samples).
max_sample_	Index of last sample to be added to batch (samples > max_sample_ will be skipped) (DEFAULT=-1 - all samples).

Member Function Documentation

template<typename eT >

bool mic::importers::CIFARImporter< eT >::importData ( )

inlinevirtual

Method responsible for importing/loading the CIFAR dataset.

Returns: TRUE if data loaded successfully, FALSE otherwise.

Implements mic::importers::Importer< mic::types::Tensor< eT >, unsigned int >.

Here is the call graph for this function:

template<typename eT >

virtual void mic::importers::CIFARImporter< eT >::initializePropertyDependentVariables ( )

inlinevirtual

Method responsible for initialization of all variables that are property-dependent - here not required, yet empty.

Definition at line 199 of file CIFARImporter.hpp.

template<typename eT >

void mic::importers::CIFARImporter< eT >::setDataFilename ( std::string data_filename_ )

inline

Set name and patch of the file/files containing CIFAR images.

Parameters

data_filename_ File (with path) containing CIFAR images. If data is supposed to be loaded from more than one files, they should be separated by a semicolon (;).
