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

java.lang.Object
es.uam.eps.ir.relison.diffusion.metrics.AbstractIndividualSimulationMetric<U,​I,​F>
es.uam.eps.ir.relison.diffusion.metrics.creator.individual.CreatorIndividualEntropy<U,​I,​F>
Type Parameters:
U - type of the users.
I - type of the information pieces.
F - type of the features.
All Implemented Interfaces:
IndividualSimulationMetric<U,​I,​F>, SimulationMetric<U,​I,​F>
public class CreatorIndividualEntropy<U extends java.io.Serializable,​I extends java.io.Serializable,​F>
extends AbstractIndividualSimulationMetric<U,​I,​F>
For each user in the network, this metric computes the entropy over the users in the network who have created an information piece that has been received by the user. If the user has not received any information piece from a creator, such creator is given the value zero. Otherwise, it takes the number of times he has received information from that user.
