calc_intersection_metrics

rectools.metrics.intersection.calc_intersection_metrics(metrics: Dict[str, Intersection], reco: DataFrame, ref_reco: Union[DataFrame, Dict[Hashable, DataFrame]]) → Dict[str, float][source]

Calculate intersection metrics.

Warning: It is not recommended to use this function directly. Use calc_metrics instead.

Parameters

  • metrics (dict(str -> IntersectionMetric)) – Dict of metric objects to calculate, where key is metric name and value is metric object.

  • reco (pd.DataFrame) – Recommendations table with columns Columns.User, Columns.Item, Columns.Rank.

  • ref_reco (Union[pd.DataFrame, Dict[Hashable, pd.DataFrame]]) – Reference recommendations table(s) with columns Columns.User, Columns.Item, Columns.Rank.

Returns

Dictionary where keys are the same as keys in metrics and values are metric calculation results.

Return type

dict(str->float)
