evaluateSend

public double evaluateSend(SocialGraphMiner socialGraphMiner,
                           eu.h2020.helios_social.core.contextualegonetwork.Context context,
                           eu.h2020.helios_social.core.contextualegonetwork.Node dst)

Description copied from interface: Measure

Supervised evaluation of interactions sent by each node.

Specified by:

evaluateSend in interface Measure

Parameters:

socialGraphMiner - The social graph miner used to perform the prediction.

context - The context in which new interactions are predicted.

dst - The destination node.

Returns:

The evaluation score - typically a value in the range [0,1], but NaN can be returned if the prediction cannot be assessed (e.g. due to invalid parameters of the measure).

lastEvaluation

public double lastEvaluation()

Description copied from interface: Measure

Retrieves the last evaluation calculated by Measure.evaluateSend(SocialGraphMiner, Context, Node).

Specified by:

lastEvaluation in interface Measure

Returns:

The las evaluation score.
