Detailed Description

column_metadata contains "meta data" concerning indexing of a single column of an SFrame. A collection of meta_data column objects is "all" the metadata required in the ml_data container.

◆ factory_create()

static std::shared_ptr<column_statistics> turi::v2::ml_data_internal::column_statistics::factory_create ( const std::map< std::string, variant_type > & creation_options )

staticinherited

The factory method for loading and instantiating the proper class

◆ finalize()

void turi::v2::ml_data_internal::basic_column_statistics::finalize ( )

virtual

Perform final computations on the different statistics. Must be called after all the data is filled.

Implements turi::v2::ml_data_internal::column_statistics.

◆ num_observations()

size_t turi::v2::ml_data_internal::basic_column_statistics::num_observations ( ) const

inlinevirtual

Returns the number of seen by the methods collecting the statistics.

Reimplemented from turi::v2::ml_data_internal::column_statistics.

Definition at line 36 of file basic_column_statistics.hpp.

◆ operator!=()

bool turi::v2::ml_data_internal::column_statistics::operator!= ( const column_statistics & other ) const

inherited

Inequality testing – slow! Use for debugging/testing

◆ operator==()

bool turi::v2::ml_data_internal::column_statistics::operator== ( const column_statistics & other ) const

inherited

Equality testing – slow! Use for debugging/testing
