Detailed Description

A very simple partitioner which partitions the data randomly into the number of desired clusters.

It has no parameters, and so an instance of the class is not even necessary.

Definition at line 26 of file random_partition.hpp.

Constructor & Destructor Documentation

◆ RandomPartition()

RandomPartition ( )
inline

Empty constructor, required by the InitialPartitionPolicy policy.

Definition at line 30 of file random_partition.hpp.

Member Function Documentation

◆ Cluster()

static void Cluster ( const MatType &  data,
const size_t  clusters,
arma::Row< size_t > &  assignments 
)
inlinestatic

Partition the given dataset into the given number of clusters.

Assignments are random, and the number of points in each cluster should be equal (or approximately equal).

Template Parameters
MatTypeType of data (arma::mat or arma::sp_mat).
Parameters
dataDataset to partition.
clustersNumber of clusters to split dataset into.
assignmentsVector to store cluster assignments into. Values will be between 0 and (clusters - 1).

Definition at line 44 of file random_partition.hpp.

◆ Serialize()

void Serialize ( Archive &  ,
const unsigned  int 
)
inline

Serialize the partitioner (nothing to do).
