- pm4py.algo.discovery.correlation_mining.algorithm.apply(log: EventLog | EventStream | DataFrame, variant=Variants.CLASSIC, parameters: Dict[Any, Any] | None = None) Tuple[Dict[Tuple[str, str], int], Dict[Tuple[str, str], float]][source]#
Applies the Correlation Miner to the event stream (a log is converted to a stream)
The approach is described in: Pourmirza, Shaya, Remco Dijkman, and Paul Grefen. “Correlation miner: mining business process models and event correlations without case identifiers.” International Journal of Cooperative Information Systems 26.02 (2017): 1742002.
- Parameters:
log – Log object
variant – Variant of the algorithm to use
parameters – Parameters of the algorithm
- Returns:
dfg – Directly-follows graph
performance_dfg – Performance DFG (containing the estimated performance for the arcs)
