This sounds really cool! I'm going to have to read up on SOMs. On Fri, Jun 7, 2013 at 9:30 AM, Amy de Buitléir wrote:

Do you have some data that you'd like to understand better? I'm happy to announce a new release of a package called som that may help:

A Kohonen Self-organising Map (SOM) maps input patterns onto a regular grid (usually two-dimensional) where each node in the grid is a model of the input data, and does so using a method which ensures that any topological relationships within the input data are also represented in the grid. This implementation supports the use of non-numeric patterns.

In layman's terms, a SOM can be useful when you want to discover the underlying structure of some data. I have a brief tutorial in the wiki, which I hope to expand over the next few weeks.

WHAT'S NEW - It is now easier to for non-math types to create a SOM (see defaultSOM) - Added another example to the wiki
