Class AggregatingCoherenceMeasure

java.lang.Object

net.sf.tweety.logics.ml.analysis.AbstractCoherenceMeasure

net.sf.tweety.logics.ml.analysis.AggregatingCoherenceMeasure

All Implemented Interfaces:

Serializable

public class AggregatingCoherenceMeasure
extends AbstractCoherenceMeasure

This coherence measure uses an aggregation function and a distance function to measure the coherence of an MLN. For each formula in the MLN the distance function looks at the probabilities of all ground instance and compares this vector to the intended probabilities. The aggregation function is used to aggregate the distances for all formulas.
