Bases: Enum

ACTIVITY_KEY = 'pm4py:param:activity_key'#

STRICT = 'strict'#

FIRST_OR_LAST = 'first_or_last'#

Filters the prefixes of an activity in the event log

Parameters#

log: Event log
activity: Target activity
parameters: Parameters of the algorithm, including: - Parameters.ACTIVITY_KEY => the activity. - Parameters.STRICT => applies the filter strictly (cuts the occurrences of the selected activity). - Parameters.FIRST_OR_LAST => decides if the first or last occurrence of an activity should be selected.

Returns#

filtered_log: Filtered event log
