Class CNetBasedOnlineMiningAlgorithm

java.lang.Object

org.processmining.stream.algorithms.OnlineMiningAlgorithm

org.processmining.stream.algorithms.CNetBasedOnlineMiningAlgorithm

Direct Known Subclasses:

BudgetLossyCountingHM, LossyCountingHM, SpaceSavingHM

public abstract class CNetBasedOnlineMiningAlgorithm
extends OnlineMiningAlgorithm

Abstract online mining class for algorithms based on CNet. The fitness and the precision values, for models computed starting from this class, require the specification of the getLogStartEnd() method.
