pm4py.analysis.compute_emd#

pm4py.analysis.compute_emd(language1: Dict[List[str], float], language2: Dict[List[str], float]) → float[source]#

Computes the earth mover distance between two stochastic languages (for example, the first extracted from the log, and the second extracted from the process model.

Parameters:

language1 – (first) stochastic language
language2 – (second) stochastic language

Return type:

float
