All Implemented Interfaces:

PipeInputIterator, Iterator

public class VenuePaperClusterIterator
extends AbstractPipeInputIterator

Iterates over PaperVenueClusters. Each instance consists of a Paper, its potential Cluster, and a Venue and its potential Cluster.

Constructor Detail

VenuePaperClusterIterator

public VenuePaperClusterIterator(Collection paperClusters,
                                 Collection venueClusters,
                                 Random r,
                                 double positiveInstanceRatio)

Randomly choose nodes and build clusters. Each time we must decide whether a node belongs in an existing cluster, we make a nodeClusterPair instance.

Parameters:

clusters - true clustering

r - for randomly selecting nodes to cluster

negativeInstanceFrequency - include negative instances with frequency 1/negativeInstanceFrequency

generateSampledInstances - sample positive instances from true clusters by sampling

sampleSize - number of training instances
