record_t

using ultra::src::record_t = std::vector<value_t>

A raw observation or data entry, typically read from an input source.

The ETL chain is: INPUT SOURCE -> raw record -> processed example –(push_back)-> dataframe raw_data/file record_t example

[in]

n

the name of a weka domain

Returns

the internal id corresponding to the weka-domain n (D_VOID if unknown / not managed)

label()

class_t ultra::src::label ( const example & e )

nodiscard
