Detailed Description

Implements all necessary data and functions needed for scaling a plssvm::data_set to an user-defined range.

Constructor & Destructor Documentation

template<typename T , typename U >

plssvm::data_set< T, U >::scaling::scaling	(	real_type	lower,
		real_type	upper
	)

Create a new scaling class that can be used to scale all features of a data set to the interval [lower, upper].

Parameters

[in]	lower	the lower bound value of all features
[in]	upper	the upper bound value of all features

Exceptions

plssvm::data_set_exception if lower is greater or equal than upper

template<typename T , typename U >

plssvm::data_set< T, U >::scaling::scaling ( const std::string & filename )

Read the scaling interval and factors from the provided file filename.

Parameters

[in] filename the filename to read the scaling information from

Exceptions

plssvm::invalid_file_format_exception all exceptions thrown by the plssvm::detail::io::parse_scaling_factors function

template<typename T , typename U >

void plssvm::data_set< T, U >::scaling::save ( const std::string & filename ) const

Save the scaling factors to the file filename.

Parameters

[in] filename the file to save the scaling factors to

Exceptions

plssvm::data_set_exception if no scaling factors are available
