Your installer $0 has a modification time in the future ($s > $t).

This is known to create infinite loops in make.

Please correct this, then run $0 again.

lib/Algorithm/KernelKMeans.pm  view on Meta::CPAN

Executes clustering. Return value is an array ref of clusters.

=head3 k

Required. (maximum) number of clusters.

=head3 k_min

Some clusters may be empty during clustering.
In the case of that, the clusterer just removes the empty clusters and checks number of rest clusters. If it is less than C<k_min>, the clusterer throws an error.

Default is same as C<k>.

=head3 shuffle

When this option is true (this is default), the clusterer sets up initial clusters by random shuffling.

If it is not what you want, you can set false and get always same result:

  use Test::More;
