Class RandomWalkGraphIteratorProvider<V>

java.lang.Object

org.deeplearning4j.graph.iterator.parallel.RandomWalkGraphIteratorProvider<V>

Type Parameters:

V - Vertex type

All Implemented Interfaces:

GraphWalkIteratorProvider<V>

public class RandomWalkGraphIteratorProvider<V>
extends java.lang.Object
implements GraphWalkIteratorProvider<V>

Random walk graph iterator provider: given a graph, split up the generation of random walks for parallel learning. Specifically: with N threads and V vertices: - First iterator generates random walks starting at vertices 0 to V/N - Second iterator generates random walks starting at vertices V/N+1 to 2*V/N - and so on

Method Detail

getGraphWalkIterators

public java.util.List<GraphWalkIterator<V>> getGraphWalkIterators(int numIterators)

Description copied from interface: GraphWalkIteratorProvider

Get a list of GraphWalkIterators. In general: may return less than the specified number of iterators, (for example, for small networks) but never more than it

Specified by:

getGraphWalkIterators in interface GraphWalkIteratorProvider<V>

Parameters:

numIterators - Number of iterators to return
