Heuristics Miner

Dummy version 1.0.0.v202003051301 by PADS RWTH Aachen

This node implements the Heuristics Miner to discover a process model. Heuristics Miner is an algorithm that acts on the directly-follows Graph, providing way to handle with noise and to find dependency between activities. An heuristics net or causal net is the output, which is a directed graph with activities as nodes, dependency interpreted as arcs and bindings. The Heuristics Net can be then converted into a Petri net.
This node shows the Heuristics Net as one internal result in View "Heuristic Net", while it outputs a Petri net after an implicit conversion.

Options

Event classifer: The event classifier is chosen to classify the event log.
All tasks connected: Every task needs to have at least one input and output arc, except the initial and the final activity.
Long distance dependency: Show long distance relations in the model.
Threshold: Relative-to-best: The admissible distance between directly follows relations for an activity and the activity's best one. At 0 only the best directly follows relation will be shown for every activity, at 100 all will be shown.
Threshold: Dependency: The strength of the directly follows relations determines when to show arcs (based on how frequently one activity is followed by another).
Threshold: Length-one-loops: Show arcs based on frequency of L1L observations
Threshold: Length-two-loops: Show arcs based on frequency of L2L observations
Threshold: Long distance: Show arcs based on how frequently one activity is eventually followed by another
