Class WeightedWalker<T extends SequenceElement>

java.lang.Object

org.deeplearning4j.models.sequencevectors.graph.walkers.impl.RandomWalker<T>

org.deeplearning4j.models.sequencevectors.graph.walkers.impl.WeightedWalker<T>

All Implemented Interfaces:

GraphWalker<T>

public class WeightedWalker<T extends SequenceElement>
extends RandomWalker<T>
implements GraphWalker<T>

This is vertex weight-based walker for SequenceVectors-based DeepWalk implementation. Instead of random walks, this walker produces walks based on weight of the edges.
