SYNOPSIS
Public Member Functions
RandomPartition ()
Empty constructor, required by the InitialPartitionPolicy policy.
Static Public Member Functions
template<typename MatType > static void Cluster (const MatType &data, const size_t clusters, arma::Col< size_t > &assignments)
Partition the given dataset into the given number of clusters.
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.

Member Function Documentation
template<typename MatType > static void mlpack::kmeans::RandomPartition::Cluster (const MatType &data, const size_tclusters, arma::Col< size_t > &assignments) [inline], [static]
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:
 MatType Type of data (arma::mat or arma::sp_mat).
Parameters:

data Dataset to partition.
clusters Number of clusters to split dataset into.
assignments Vector to store cluster assignments into. Values will be between 0 and (clusters  1).
