Package org.processmining.stochasticlabelleddatapetrinet.weights.fitting

Class LogisticRegressionWeightFitter

java.lang.Object

org.processmining.stochasticlabelleddatapetrinet.weights.fitting.LogisticRegressionWeightFitter

All Implemented Interfaces:

WeightFitter

public class LogisticRegressionWeightFitter
extends java.lang.Object
implements WeightFitter

Fits a logistic regression using WEKA to the observations and adds the respective WeightFunction to the transitions. Assumes that transition labels and variable names in the given SLDPN exactly match the attributes in the event log based on the provided classifier.
