Constructor Detail

OptimalMiner

public OptimalMiner(DistanceFunction function,
                    org.processmining.framework.plugin.PluginContext context,
                    org.deckfour.xes.model.XLog log,
                    M model)

Method Detail

computeDistance

protected abstract Distance computeDistance(org.deckfour.xes.model.XLog log,
                                            M model)

Computes the distance between a log and a model Subclasses need to implement this according to their model type. Ideally, this is a fast step.

Parameters:

log - the log to compare with the model

model - the model to compare with the log

Returns:

Distance

getBestLog

public org.deckfour.xes.model.XLog getBestLog()

getBestModel

public M getBestModel()

searchForBetterLogAndModel

public void searchForBetterLogAndModel()

performSearch

protected abstract void performSearch()

Tries to find a log-model pair that is best in terms of a score
