Discovering of the unobservable behaviour of an Interpreted Petri Net model

This paper focuses on the problem of discovering a Petri Net model from long event sequences generated by a discrete event system. Precisely, it is assumed that the behavior of the relations between input and output events (i.e. the observable…
