java.lang.Object
  netkit.classifiers.aggregators.AggregatorImp
      netkit.classifiers.aggregators.Mode

All Implemented Interfaces:

Aggregator

public final class Mode
extends AggregatorImp

The Mode aggregator counts the number of times each possible value of a given attribute is observed in the neighborhood of a node in the graph and returns the value that is observed the most. If there is a tie then the value is returned through a stochastic process.
