Detailed Description

template<class VectorType, class CenterOfMassInitializer>
class SBL::GT::T_Cluster_engine_k_means_com_Sd< VectorType, CenterOfMassInitializer >

Representation of a center of mass in k-means algorithm.

Representation of a center of mass for k-means on the unit sphere S^d.

The representation used for a center on the unit sphere S^d. must provide a += operation since we accumulate points on a center. Also expected is a functor to initialize the center of mass on the unit sphere–an operation depending on the type used.

Template Parameters

PointType	Representation of a point.
VectorType	Representation of a vector.
