Additional details

Authors of emeans

emeans is written and maintained by James Joseph Balamuta: the R port of
the algorithm, the C++ assignment kernels in src/, the torch backend, the
em_*() batch loop, the broom and tidyclust methods, the documentation and
the tests.

Ported code

The algorithm is ported from the Python implementation of e-means in faiss
contrib/e_means (https://github.com/facebookresearch/faiss), written by
Gergely Szilvasy, Swann Bessa and Matthijs Douze. The files derived from it
are listed in inst/COPYRIGHTS. They are credited as contributors for that
code only and took no part in writing, reviewing or maintaining this package,
so please report problems with it at
