    Description

      It had been noted (cf. other JIRA reports) quite some ago that the API defined in package o.a.c.math4.ml.clustering could be improved.
      Interest in this code has been recently renewed (cf. this thread on the "dev" ML).

      This report will collect specific refactoring tasks.

      Linked reports should serve as a guide towards a flexible API and efficient implementations.
