Method Detail

numDimensions

public int numDimensions()

Description copied from interface: SpatialClusters

Get the data dimensionality

Specified by:

numDimensions in interface SpatialClusters<double[]>

Returns:

the data dimensionality.

defaultHardAssigner

public HardAssigner<double[],?,?> defaultHardAssigner()

Description copied from interface: SpatialClusters

Get the default hard assigner for this clusterer. This method is potentially expensive, so callers should only call it once, and hold on to the result (and reuse it).

Specified by:

defaultHardAssigner in interface SpatialClusters<double[]>

Returns:

a hard assigner.
