# The hsgsom package

The growing self organising map (GSOM) algorithm is a clustering algorithm
working on a set of n-dimensional numeric input vectors. It's output is a
network of nodes laid out in two dimensions where each node has a weight
vector associated with it. This weight vector has the same dimension as the
input vectors and is meant to be intepreted as a cluster center, i.e. it
represents those input vectors whose distance to the node's weight vector
is minimal when compared to the distance to the other nodes weight vectors.
See http://en.wikipedia.org/wiki/GSOM for an explanation of the algorithm.
The algorithm was introduced in:
Alahakoon, D., Halgamuge, S. K. and Sirinivasan, B. (2000)
Dynamic Self Organizing Maps With Controlled Growth
for Knowledge Discovery,

= README
This is the README file of hsgsom, a haskell library implementing the
growing self organising map clustering algorithm.
== The Algorithm

== License
This package and its contents are licensed under the BSD 3 clause license.
You should have received a file called LICENSE containing said license
along with this package.
== Versioning
This README correponds to version 0.1.0 of hsgsom, so as you can see it is
a very early version.
Version numbers follow the pattern X.Y.Z and have the following meaning:
- a change in Z corresponds to minor changes as in documentation changes
or changes to the underlying implementation
- a change in Y correponds to added functionality and/or backwards
compatible interface changes/additions.
- a change in X correpsonds to a major implementation change either
drastically changing the algorithm behaviour or performance or
changing the interface in a possibly not backwards compatible way.
== Questions, Bugs, etc...
If you think you have found a bug, or you have questions or suggestions
or really anything to say about the package it would be greatly appreciated
if you would drop me a note or an email.
This is my very firt attempt at packaging and releasing a substantial amount
my own code to the public and I'm eager to learn how to do thinks better.
Thanks for using/looking at this package and have a nice day.
