SOM in scipy.cluster
Greetings, I'm considering using self-organizing maps for mining some lightning data, and info.py in scipy.cluster mentions that implementation of self-organizing maps is under development. I've found a few examples written in python around the web, but none that are likely to be efficient enough for my use. Is there still interest in including SOM in scipy? I'd be happy to coordinate on a contribution if nothing else is under way. Thanks, Eric

Sure! My colleague Corran Webster was thinking about doing some SOM stuff for scipy, too, so you two should talk. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
Hi, SOM were supposed to be included in scikits.learn, weren't they ? (as scipy.cluster is in scipy only for historical reasons) Matthieu 2008/8/13 Robert Kern <robert.kern@gmail.com>:

It depends. I think Corran's proposal to put a simple and fast batch SOM algorithm in scipy.cluster.vq and more general variations of the SOM algorithm in the scikit is a good approach. In general, it is OK to improve the cluster package in scipy. For instance, I think Damian's hierarchical clustering code (http://projects.scipy.org/scipy/scipy/browser/trunk/scipy/cluster/hierarchy....) is a good example of what should go into scipy.cluster. -- Jarrod Millman Computational Infrastructure for Research Labs 10 Giannini Hall, UC Berkeley phone: 510.643.4014 http://cirl.berkeley.edu/
