Seasonal

class getml.preprocessors.Seasonal

Bases: getml.preprocessors.preprocessor._Preprocessor

The Seasonal preprocessor extracts seasonal data from time stamps.

The preprocessor automatically iterates through all time stamps in any data frame and extracts seasonal parameters.

These include:

• year

• month

• weekday

• hour

• minute

The algorithm also evaluates the potential usefulness of any extracted seasonal parameter. Parameters that are unlikely to be useful are not included.

Example:

seasonal = getml.preprocessors.Seasonal()

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