Detailed Description

template<typename T, typename MapperType, typename StrategyType>
class mlpack::data::Imputer< T, MapperType, StrategyType >

Given a dataset of a particular datatype, replace user-specified missing value with a variable dependent on the StrategyType and MapperType.

Template Parameters

T	Type of armadillo matrix used for imputation strategy.
MapperType	DatasetMapper that is used to hold dataset information.
StrategyType	Imputation strategy used.

Member Function Documentation

template<typename T , typename MapperType , typename StrategyType >

void mlpack::data::Imputer< T, MapperType, StrategyType >::Impute ( arma::Mat< T > &  input, const std::string &  missingValue, const size_t  dimension  )

inline

Given an input dataset, replace missing values of a dimension with given imputation strategy.

This function does not produce output matrix, but overwrites the result into the input matrix.

Parameters

input	Input dataset to apply imputation. missingValue User defined missing value; it can be anything.
dimension	Dimension to apply the imputation.
