# mlpack\_kmeans\_RandomPartition(3)

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

## NAME

mlpack::kmeans::RandomPartition -

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

## 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.

## Constructor & Destructor Documentation

### mlpack::kmeans::RandomPartition::RandomPartition ()` [inline]`

Empty constructor, required by the InitialPartitionPolicy policy.

Definition at line 40 of file random\_partition.hpp.

## 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).
