## Detailed Description

Kmeans clusterer: This clusterer implements the K-Means clustering algorithm.

## Constructor & Destructor Documentation

## ◆ KMeans()

Xapian::KMeans::KMeans | ( | unsigned int | k_,
|  | unsigned int | max_iters_ = 0 )
| explicit

Constructor specifying number of clusters and maximum iterations.

Parameters

  k_ | Number of required clusters
  max_iters_ | The maximum number of iterations for which KMeans will run if it doesn't converge

## Member Function Documentation

## ◆ cluster()

ClusterSet Xapian::KMeans::cluster | ( | const MSet & | mset | ) |
| override virtual

Implements the KMeans clustering algorithm.

Parameters

  mset | MSet object containing the documents that are to be clustered

Implements Xapian::Clusterer.

## ◆ get_description()

std::string Xapian::KMeans::get_description | ( |  | ) | const
| override virtual

Return a string describing this object.

Implements Xapian::Clusterer.

## ◆ set_stopper()

void Xapian::KMeans::set_stopper | ( | const Xapian::Stopper * | stop = NULL | ) |
| inline

Set the Xapian::Stopper object to be used for identifying stopwords.

Stopwords are discarded while calculating term frequency for terms.

Parameters

  stop | The Stopper object to set (default NULL, which means no stopwords)
