EmailDomain

class getml.preprocessors.EmailDomain

Bases: getml.preprocessors.preprocessor._Preprocessor

The EmailDomain preprocessor extracts the domain from e-mail addresses.

For instance, if the e-mail address is ‘some.guy@domain.com’, the preprocessor will automatically extract ‘@domain.com’.

The preprocessor will be applied to all text columns that were assigned one of the subroles getml.data.subroles.include.email or getml.data.subroles.only.email.

It is recommended that you assign getml.data.subroles.only.email, because it is unlikely that the e-mail address itself is interesting.

Example:

my_data_frame.set_subroles("email", getml.data.subroles.only.email)

domain = getml.preprocessors.EmailDomain()

pipe = getml.Pipeline(
    population=population_placeholder,
    peripheral=[order_placeholder, trans_placeholder],
    preprocessors=[domain],
    feature_learners=[feature_learner_1, feature_learner_2],
    feature_selectors=feature_selector,
    predictors=predictor,
    share_selected_features=0.5
)
