-- A Simplified Self-organising Map (SSOM). An SSOM maps input patterns
-- onto a set, where each element in the set is a model of the input
-- data. An SSOM is like a Kohonen Self-organising Map (SOM), except
-- that instead of a grid, it uses a simple set of unconnected models.
-- Since the models are unconnected, only the model that best matches
-- the input is ever updated. This makes it faster, however,
-- topological relationships within the input data are not preserved.
-- This implementation supports the use of non-numeric patterns.
--
-- In layman's terms, a SSOM can be useful when you you want to build
-- a set of models on some data. A tutorial is available at
-- <https://github.com/mhwombat/som/wiki>.
