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)
