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_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

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).
