Method Summary

Modifier and Type	Method	Description
double	evaluateSend(SocialGraphMiner socialGraphMiner, eu.h2020.helios_social.core.contextualegonetwork.Context context, eu.h2020.helios_social.core.contextualegonetwork.Node dst)	Supervised evaluation of interactions sent by each node.
default double	lastEvaluation()	Retrieves the last evaluation calculated by evaluateSend(SocialGraphMiner, Context, Node).

Method Detail

evaluateSend

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

Supervised evaluation of interactions sent by each node.

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

default double lastEvaluation()

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

Returns:

The las evaluation score.

Throws:

java.lang.RuntimeException - if this method is not implemented.
