Class CreatorGlobalEntropy<U extends java.io.Serializable,​I extends java.io.Serializable,​F>

java.lang.Object
es.uam.eps.ir.relison.diffusion.metrics.AbstractGlobalSimulationMetric<U,​I,​F>
es.uam.eps.ir.relison.diffusion.metrics.creator.global.CreatorGlobalEntropy<U,​I,​F>
Type Parameters:
U - type of the user.
I - type of the information.
F - type of the features.
All Implemented Interfaces:
GlobalSimulationMetric<U,​I,​F>, SimulationMetric<U,​I,​F>
public class CreatorGlobalEntropy<U extends java.io.Serializable,​I extends java.io.Serializable,​F>
extends AbstractGlobalSimulationMetric<U,​I,​F>
Computes the entropy over the set of users in the network. For each user, the value is the number of created pieces which have been received by other users.
