pm4py.algo.filtering.log.end_activities.end_activities_filter.apply(log: EventLog, admitted_end_activities: List[str], parameters: Dict[str | Parameters, Any] | None = None) → EventLog[source]#

Filter the log on the specified end activities

Parameters:

  • log – Log

  • admitted_end_activities – Admitted end activities

  • parameters – Algorithm parameters

Returns:

Filtered log

Return type:

filtered_log

pm4py.algo.filtering.log.end_activities.end_activities_filter.filter_log_by_end_activities(end_activities, variants, vc, threshold, activity_key='concept:name')[source]#

Keep only variants of the log with an end activity which number of occurrences is above the threshold

Parameters:

  • end_activities – Dictionary of end attributes associated with their count

  • variants – (If specified) Dictionary with variant as the key and the list of traces as the value

  • vc – List of variant names along with their count

  • threshold – Cutting threshold (remove variants having end attributes which number of occurrences is below the threshold

  • activity_key – (If specified) Specify the activity key in the log (default concept:name)

Returns:

Filtered log

Return type:

filtered_log
