class ClusteringModel extends Model with HasWrappedClusteringAttributes
A cluster model basically consists of a set of clusters. For each cluster a center vector can be given. In center-based models a cluster is defined by a vector of center coordinates. Some distance measure is used to determine the nearest center, that is the nearest cluster for a given input record. For distribution-based models (e.g., in demographic clustering) the clusters are defined by their statistics. Some similarity measure is used to determine the best matching cluster for a given record. The center vectors then only approximate the clusters.

When Target specifies optype then it overrides the optype attribute in a corresponding MiningField, if it exists. If the target does not specify optype then the MiningField is used as default. And, in turn, if the MiningField does not specify an optype, it is taken from the corresponding DataField. In other words, a MiningField overrides a DataField, and a Target overrides a MiningField.
