Adriansyah Escaping-Edge (ETC) Precision Engine with Inductive Negative Event Weighting. Faithful BEAM realization of Adriansyah, Dongen, and Van der Aalst (2012, 2014).
Computes process model precision by measuring "escaping edges" (transitions enabled in the model at each alignment state that were never observed in the log):
Precision_ETC(L, N, α) = 1.0 - (Σ |EscapingEdges(s)| / (Σ |EnabledTransitions(s)| + α · |Refused(s)|))
Summary
Functions
Calculates the Escaping-Edge ETC Precision of a Workflow Net against an event log (list of traces).
Supports :negative_event_weight (alpha) for smoothing against sparse event logs.
