eu.h2020.helios_social.modules.socialgraphmining.GNN.TrainingExample

public class TrainingExample
extends java.lang.Object

A class models a training example used in GNN architectures that can be written a tuple (src, dst, weight, label). The source and destination node pairs cannot be modeled through an Interaction of the contextual ego network module, because they also include potentially negative examples.
