pm4py.util.variants_util.aggregate_consecutive_activities_in_variants(variants: Dict[Collection[str], int | List], max_repetitions: int = 1) → Dict[Collection[str], int | List]

Aggregate the consecutive activities in the variant.

For example, {(‘A’, ‘B’, ‘C’): 3, (‘A’, ‘B’, ‘B’, ‘B’, ‘C’): 2, (‘A’, ‘B’, ‘B’, ‘B’, ‘B’, ‘B’, ‘C’): 1} Would be reduced to: - {(‘A’, ‘B’, ‘C’): 6} if max_repetitions=1 - {(‘A’, ‘B’, ‘C’): 3, (‘A’, ‘B’, ‘B’, ‘C’): 3} if max_repetitions=2 - {(‘A’, ‘B’, ‘C’): 3, (‘A’, ‘B’, ‘B’, ‘B’, ‘C’): 3} if max_repetitions=3 - {(‘A’, ‘B’, ‘C’): 3, (‘A’, ‘B’, ‘B’, ‘B’, ‘C’): 2, (‘A’, ‘B’, ‘B’, ‘B’, ‘B’, ‘C’): 1} if max_repetitions=4

Parameters:

• variants – Dictionary of variants (where each variant is associated to its count (pd.DataFrame) or the list of traces (EventLog))

• max_repetitions – Maximum number of consecutive repetitions for an activity

Returns:

Dictionary of variants aggregated based on the limit of consecutive repetitions for the same activity

Return type:

aggregated_variants
