es.uam.eps.ir.relison.diffusion.metrics.features.AbstractFeatureIndividualSimulationMetric<U,I,P>

es.uam.eps.ir.relison.diffusion.metrics.features.indiv.AbstractExternalFeatureIndividualSimulationMetric<U,I,P>

Type Parameters:

U - type of the users.

I - type of the information pieces.

P - type of the user / information pieces features.

All Implemented Interfaces:

IndividualSimulationMetric<U,I,P>, SimulationMetric<U,I,P>

Direct Known Subclasses:

ExternalFeatureIndividualGiniComplement, ExternalFeatureIndividualRate, ExternalFeatureRecall

public abstract class AbstractExternalFeatureIndividualSimulationMetric<U extends java.io.Serializable,I extends java.io.Serializable,P>
extends AbstractFeatureIndividualSimulationMetric<U,I,P>

Abstract class representing individual feature-based metrics which do not take into account features that the user already knows (with already knows meaning that the user has the feature, in case of user features, or the user has an information piece containing the feature, in case of information features).

Constructor Details

AbstractExternalFeatureIndividualSimulationMetric

public AbstractExternalFeatureIndividualSimulationMetric(java.lang.String name, java.lang.String parameter, boolean userparam)

Constructor.

Parameters:

name - Name of the metric.

parameter - Name of the metric parameter.

userparam - True if the parameter is a user parameter, false if it is not.

Method Details

getOwnFeats

protected java.util.Map<U,java.util.Set<P>> getOwnFeats()

Obtains the map identifying the features of all users.

Returns:

the features of all users.

getOwnFeats

protected java.util.Set<P> getOwnFeats(U u)

Obtains the features that an individual user already knows.

Parameters:

u - the user.

Returns:

the set of features the user already knows. If the user does not exist, an empty set is returned.

computeOwnFeatures

protected void computeOwnFeatures()

Computes and stores the own features for every user in the network.

computeOwnFeatures

protected java.util.Set<P> computeOwnFeatures(U u)

Computes the features for a user

Parameters:

u - the user.

Returns:

the feature set for the user

computeOwnUserFeatures

protected java.util.Set<P> computeOwnUserFeatures(U u)

Computes the user features for an individual user.

Parameters:

u - the user.

Returns:

the feature set.

computeOwnInfoFeatures

protected java.util.Set<P> computeOwnInfoFeatures(U u)

Computes information piece features for an individual user.

Parameters:

u - the user.

Returns:

the feature set.

clearOwnFeatures

protected void clearOwnFeatures()

Clears all the information pieces features of all users.

setOwnFeatures

protected void setOwnFeatures(U u, java.util.Set<P> features)

Adds features for an individual user.

Parameters:

u - the user.

features - the features.
