New issue 10 by kyle.tha...@gmail.com: Handle categorical data
http://code.google.com/p/ifcsoft/issues/detail?id=10
IFC Soft should be able to load data with categorical dimensions (both by
string or by number). The SOM algorithm should treat being in a different
category as being a distance of 1. The program should let you select groups
of data points or data sets by the categories and make hit histograms based
on them.
I started a thread to discuss how to solve this and issue 9:
