score

Pipeline.score(population_table: Union[getml.data.data_frame.DataFrame, getml.data.view.View, getml.data.subset.Subset], peripheral_tables: Optional[Union[Dict[str, Union[getml.data.data_frame.DataFrame, getml.data.view.View]], Sequence[Union[getml.data.data_frame.DataFrame, getml.data.view.View]]]] = None) → getml.pipeline.scores_container.Scores

Calculates the performance of the predictor.

Returns different scores calculated on population_table and peripheral_tables.

Args:

population_table (DataFrame, View or Subset):

Main table containing the target variable(s) and corresponding to the population Placeholder instance variable.

peripheral_tables (List[DataFrame or View], dict, DataFrame or View, optional):

Additional tables corresponding to the peripheral Placeholder instance variable. If passed as a list, the order needs to match the order of the corresponding placeholders passed to peripheral.

If you pass a Subset to population_table, the peripheral tables from that subset will be used. If you use a Container, StarSchema or TimeSeries, that means you are passing a Subset.

Note:

Only fitted pipelines (fit()) can be scored.
