[DM] Are all subgroup discovery algorithms supervised?

This question is addressed to Subgroup Discovery experts. Are all SD algorithms supervised? When I run the following DL Query in DMOP:

DM-Algorithm and specifiesInputType some CategoricalLabeledDataSet

I get a list including:

  • ClassificationModelingAlgorithm (and all its subclasses and instances)
  • CN2-SD-Algorithm
  • SD-Algorithm

but not SubgroupDiscoveryAlgorithm.

This implies that there are or can be unsupervised subgroup discovery algorithms. Is this correct?

In the absence of feedback, I'm replying to my own question. It seems subgroup discovery is by definition supervised.(Atzmueller 2005, Lavrac et al., 2004).
