Definition at line 76 of file param.hpp.

◆ PARAM_COL

#define PARAM_COL	(	ID,
		DESC,
		ALIAS,
		REQ,
		TRANS,
		IN
	)

Value:

static mlpack::util::Option \
      JOIN(io_option_dummy_object_col_, __LINE__) \
      (arma::vec(), ID, DESC, ALIAS, "arma::vec", REQ, IN, !TRANS, \
      testName);

Definition at line 1305 of file param.hpp.

◆ PARAM_COL_IN

#define PARAM_COL_IN	(	ID,
		DESC,
		ALIAS
	)	PARAM_COL(ID, DESC, ALIAS, false, true, true)

Define a vector input parameter (type arma::vec).

From the command line, the user can specify the file that holds the vector, using the name of the vector parameter with "_file" appended (and the same alias). So for instance, if the name of the vector parameter was "vec", the user could specify that the "vec" vector was held in vec.csv by giving the parameter:

--vec_file vector.csv

Parameters

ID	Name of the parameter.
DESC	Description of the parameter (1-2 sentences). Don't use printing macros like PRINT_PARAM_STRING() or PRINT_DATASET() or others here—it will cause problems.
ALIAS	An alias for the parameter (one letter).

Bug:: The COUNTER variable is used in most cases to guarantee a unique global identifier for options declared using the PARAM_*() macros. However, not all compilers have this support–most notably, gcc < 4.3. In that case, the LINE macro is used as an attempt to get a unique global identifier, but collisions are still possible, and they produce bizarre error messages. See https://github.com/mlpack/mlpack/issues/100 for more information.

Definition at line 670 of file param.hpp.

◆ PARAM_COL_IN_REQ

#define PARAM_COL_IN_REQ	(	ID,
		DESC,
		ALIAS
	)	PARAM_COL(ID, DESC, ALIAS, true, true, true)

Define a required vector input parameter (type arma::vec).

From the command line, the user can specify the file that holds the vector, using the name of the vector parameter with "_file" appended (and the same alias). So for instance, if the name of the vector parameter was "vec", the user could specify that the "vec" vector was held in vec.csv by giving the parameter:

--vec_file vector.csv

Parameters

ID	Name of the parameter.
DESC	Description of the parameter (1-2 sentences). Don't use printing macros like PRINT_PARAM_STRING() or PRINT_DATASET() or others here—it will cause problems.
ALIAS	An alias for the parameter (one letter).

◆ PARAM_COL_OUT

#define PARAM_COL_OUT	(	ID,
		DESC,
		ALIAS
	)	PARAM_COL(ID, DESC, ALIAS, false, true, false)

Define a vector output parameter (type arma::vec).

When the program terminates, the vector will be saved to whatever it was set to during the program. From the command-line, the user may specify the file in which to save the output vector using a string option that is the name of the matrix parameter with "_file" appended. So, for instance, if the name of the output vector parameter was "vec", the user could specify that the "vec" vector should be saved in vector.csv by giving the parameter:

--vec_file vector.csv

The output vector will not be printed on stdout, like the other output option types.

Parameters

ID	Name of the parameter.
DESC	Description of the parameter (1-2 sentences). Don't use printing macros like PRINT_PARAM_STRING() or PRINT_DATASET() or others here—it will cause problems.
ALIAS	An alias for the parameter (one letter).

#define PARAM_DOUBLE_IN	(	ID,
		DESC,
		ALIAS,
		DEF
	)	PARAM_IN(double, ID, DESC, ALIAS, DEF, false)

Define a double input parameter.

The parameter can then be specified on the command line with –ID=value.

Parameters

ID	Name of the parameter.
DESC	Quick description of the parameter (1-2 sentences). Don't use printing macros like PRINT_PARAM_STRING() or PRINT_DATASET() or others here—it will cause problems.
ALIAS	An alias for the parameter (one letter).
DEF	Default value of the parameter.

◆ PARAM_DOUBLE_OUT

#define PARAM_DOUBLE_OUT	(	ID,
		DESC
	)	PARAM_OUT(double, ID, DESC, "", 0.0, false)

      JOIN(JOIN(io_option_dummy_object_in_, __LINE__), opt) \
      (DEF, ID, DESC, ALIAS, #T, REQ, true, false, testName);

Define an input parameter.

Don't use this function; use the other ones above that call it. Note that we are using the LINE macro for naming these actual parameters when COUNTER does not exist, which is a bit of an ugly hack... but this is the preprocessor, after all. We don't have much choice other than ugliness.

Parameters

T	Type of the parameter.
ID	Name of the parameter.
DESC	Description of the parameter (1-2 sentences). Don't use printing macros like PRINT_PARAM_STRING() or PRINT_DATASET() or others here—it will cause problems.

	)	PARAM_MATRIX(ID, DESC, ALIAS, false, true, true)

Define a matrix input parameter.

From the command line, the user can specify the file that holds the matrix, using the name of the matrix parameter with "_file" appended (and the same alias). So for instance, if the name of the matrix parameter was "mat", the user could specify that the "mat" matrix was held in matrix.csv by giving the parameter

--mat_file matrix.csv

Parameters

ID	Name of the parameter.
DESC	Description of the parameter (1-2 sentences). Don't use printing macros like PRINT_PARAM_STRING() or PRINT_DATASET() or others here—it will cause problems.
ALIAS	An alias for the parameter (one letter).

Bug:: The COUNTER variable is used in most cases to guarantee a unique global identifier for options declared using the PARAM_*() macros. However, not all compilers have this support–most notably, gcc < 4.3. In that case, the LINE macro is used as an attempt to get a unique global identifier, but collisions are still possible, and they produce bizarre error messages. See https://github.com/mlpack/mlpack/issues/100 for more information.

#define PARAM_MATRIX_OUT	(	ID,
		DESC,
		ALIAS
	)	PARAM_MATRIX(ID, DESC, ALIAS, false, true, false)

Define a matrix output parameter.

When the program terminates, the matrix will be saved to whatever it was set to by IO::GetParam(ID) during the program. From the command-line, the user may specify the file in which to save the output matrix using a string option that is the name of the matrix parameter with "_file" appended. So, for instance, if the name of the output matrix parameter was "mat", the user could speicfy that the "mat" matrix should be saved in matrix.csv by giving the parameter

	)	PARAM_MODEL(TYPE, ID, DESC, ALIAS, false, true)

Define an input model.

From the command line, the user can specify the file that holds the model, using the name of the model parameter with "_file" appended (and the same alias). So for instance, if the name of the model parameter was "model", the user could specify that the "model" model was held in model.bin by giving the parameter

--model_file model.bin

Note that the first parameter of this model is the type (the class name) of the model to be loaded. This model type must have a serialize() function; a compilation error (a very long and complex one) will result if the model type does not have the following function:

template<typename Archive>

Bug:: The COUNTER variable is used in most cases to guarantee a unique global identifier for options declared using the PARAM_*() macros. However, not all compilers have this support–most notably, gcc < 4.3. In that case, the LINE macro is used as an attempt to get a unique global identifier, but collisions are still possible, and they produce bizarre error messages. See https://github.com/mlpack/mlpack/issues/100 for more information.

◆ PARAM_VECTOR_IN

#define PARAM_VECTOR_IN	(	T,
		ID,
		DESC,
		ALIAS
	)	PARAM_IN(std::vector, ID, DESC, ALIAS, std::vector(), false)

Define a std::vector input parameter.

The parameter can then be specified on the command line with –ID=value1,value2,value3.

Parameters

T	Type of the parameter.
ID	Name of the parameter.
DESC	Quick description of the parameter (1-2 sentences). Don't use printing macros like PRINT_PARAM_STRING() or PRINT_DATASET() or others here—it will cause problems.
ALIAS	An alias for the parameter (one letter).

◆ PARAM_VECTOR_IN_REQ

#define PARAM_VECTOR_IN_REQ	(	T,
		ID,
		DESC,
		ALIAS
	)	PARAM_IN(std::vector, ID, DESC, ALIAS, std::vector(), true);

Define a required vector parameter.

The parameter must then be specified on the command line with –ID=value1,value2,value3.

Parameters

T	Type of the parameter.
ID	Name of the parameter.
DESC	Quick description of the parameter (1-2 sentences). Don't use printing macros like PRINT_PARAM_STRING() or PRINT_DATASET() or others here—it will cause problems.
ALIAS	An alias for the parameter (one letter).

◆ PARAM_VECTOR_OUT

#define PARAM_VECTOR_OUT	(	T,
		ID,
		DESC,
		ALIAS
	)	PARAM_OUT(std::vector, ID, DESC, ALIAS, std::vector(), false)

Define a vector output parameter.

This vector will be printed on stdout at the end of the program; for instance, if the parameter name is "vector" and the vector holds the array { 1, 2, 3, 4 }, the output on stdout would be of the following form:

vector: 1, 2, 3, 4

If the parameter is not set by the end of the program, a fatal runtime error will be issued.

Parameters

T	Type of the parameter.
ID	Name of the parameter.
DESC	Quick description of the parameter (1-2 sentences). Don't use printing macros like PRINT_PARAM_STRING() or PRINT_DATASET() or others here—it will cause problems.
ALIAS	An alias for the parameter (one letter).

◆ TUPLE_TYPE

#define TUPLE_TYPE std::tuple<mlpack::data::DatasetInfo, arma::mat>

Define an input DatasetInfo/matrix parameter.

From the command line, the user can specify the file that holds the matrix, using the name of the matrix parameter with "_file" appended (and the same alias). So for instance, if the name of the matrix parameter was "matrix", the user could specify that the "matrix" matrix was held in file.csv by giving the parameter

--matrix_file file.csv

Then the DatasetInfo and matrix type could be accessed with

DatasetInfo d = std::move(
    IO::GetParam>("matrix").get<0>());
arma::mat m = std::move(
    IO::GetParam>("matrix").get<1>());

Parameters

ID	Name of the parameter.
DESC	Quick description of the parameter (1-2 sentences). Don't use printing macros like PRINT_PARAM_STRING() or PRINT_DATASET() or others here—it will cause problems.
ALIAS	One-character string representing the alias of the parameter.
