Create a new instance.

=head2 add_document($id, $vector)

Add an input document to the instance of Algorithm::Kmeanspp. $id parameter is the identifier of a document, and $vector parameter is the feature vector of a document. $vector parameter must be a hash reference, each key of $vector parameter is the i...

=head2 do_clustering($num_cluster, $num_iter)

Do clustering input documents. $num_cluster parameter specifies the number of output clusters, and $num_iter parameter specifies the number of clustering iterations.

=head2 clusters

This method is the accessor of clustering result. The output of the method is a array reference, and each item in the array reference includes the list of the identifiers of input documents in each cluster.

  # format of output clusters
  [
      [ document_id1, document_id2, ... ],  # cluster-1
      [ document_id3, document_id4, ... ],  # cluster-2
      ...
