public class SubspaceClusterDefinition
extends ClusterDefinition

A single cluster for the SubspaceCluster data generator.

Valid options are:

 -A <range>
  Uses a random uniform distribution for the instances in the cluster.

 -U <range>
  Generates totally uniformly distributed instances in the cluster.

 -G <range>
  Uses a Gaussian distribution for the instances in the cluster.

 -D <num>,<num>
  The attribute min/max (-A and -U) or mean/stddev (-G) for the cluster, repeated for each attribute.

 -N <num>..<num>
  The range of number of instances per cluster (default 1..50).

 -I
  Uses integer instead of continuous values (default: continuous).
