Examples of org.apache.mahout.clustering.Cluster

org.apache.mahout.clustering.Cluster
Implementations of this interface have a printable representation and certain attributes that are common across all clustering implementations

    models = Lists.newArrayList();
    ClusteringPolicyWritable clusteringPolicyWritable = new ClusteringPolicyWritable();
    clusteringPolicyWritable.readFields(in);
    policy = clusteringPolicyWritable.getValue();
    for (int i = 0; i < size; i++) {
      Cluster element = ClassUtils.instantiateAs(modelClass, Cluster.class);
      element.readFields(in);
      models.add(element);
    }
