es.uam.eps.ir.relison.diffusion.metrics.features.AbstractFeatureGlobalSimulationMetric<U,​I,​P>
es.uam.eps.ir.relison.diffusion.metrics.features.global.FeatureGlobalUserEntropy<U,​I,​P>
Type Parameters:
U - type of the user.
I - type of the information.
P - type of the parameters.
All Implemented Interfaces:
GlobalSimulationMetric<U,​I,​P>, SimulationMetric<U,​I,​P>
public class FeatureGlobalUserEntropy<U extends java.io.Serializable,​I extends java.io.Serializable,​P>
extends AbstractFeatureGlobalSimulationMetric<U,​I,​P>
Computes the entropy over the different features. For each feature value, it counts the number of (different) users who have received the feature.
