pm4py.algo.filtering.pandas.paths.paths_filter.apply(df: DataFrame, paths: List[Tuple[str, str]], parameters: Dict[str | Parameters, Any] | None = None) → DataFrame[source]#

Apply a filter on traces containing / not containing a path

Parameters:

  • df – Dataframe

  • paths – Paths to filter on

  • parameters –

    Possible parameters of the algorithm, including:

    Parameters.CASE_ID_KEY -> Case ID column in the dataframe Parameters.ATTRIBUTE_KEY -> Attribute we want to filter Parameters.POSITIVE -> Specifies if the filter should be applied including traces (positive=True) or excluding traces (positive=False)

Returns:

Filtered dataframe

Return type:

df

pm4py.algo.filtering.pandas.paths.paths_filter.apply_performance(df: DataFrame, provided_path: Tuple[str, str], parameters: Dict[str | Parameters, Any] | None = None) → DataFrame[source]#

Filters the cases of a dataframe where there is at least one occurrence of the provided path occurring in the defined timedelta range.

Parameters:

  • df – Dataframe

  • paths – Paths to filter on

  • parameters –

    Possible parameters of the algorithm, including:

    Parameters.CASE_ID_KEY -> Case ID column in the dataframe Parameters.ATTRIBUTE_KEY -> Attribute we want to filter Parameters.TIMESTAMP_KEY -> Attribute identifying the timestamp in the log Parameters.POSITIVE -> Specifies if the filter should be applied including traces (positive=True) or excluding traces (positive=False) Parameters.MIN_PERFORMANCE -> Minimal allowed performance of the provided path Parameters.MAX_PERFORMANCE -> Maximal allowed performance of the provided path

Returns:

Filtered dataframe

Return type:

df
