Method Detail

getPrototype

public static <V extends NumberVector> V getPrototype(Model model,
                                                      Relation<? extends V> relation,
                                                      NumberVector.Factory<V> factory)

Get (and convert!) the representative vector for a cluster model. Only representative-based models are supported! null is returned when the model is not supported!

Type Parameters:

V - desired vector type

Parameters:

model - Model

relation - Data relation (for representatives specified per DBID)

factory - Vector factory, for type conversion.

Returns:

Vector of type V, null if not supported.

getPrototype

public static NumberVector getPrototype(Model model,
                                        Relation<? extends NumberVector> relation)

Get (and convert!) the representative vector for a cluster model. Only representative-based models are supported! null is returned when the model is not supported!

Parameters:

model - Model

relation - Data relation (for representatives specified per DBID)

Returns:

Some NumberVector, null if not supported.
