A toolbox to implement Spherical Self-Organizing Feature Maps


Updated 15 Dec 2006

The Spherical Self-Organizing Feature Maps is a contemporary technique for data clustering and visualization.

The main advantages they offer are the following:
1. Smooth training
2. Implementation in arbitrary dimension without additional computational cost.
3. Data visualization in arbitrary dimensions

This toolbox contains a set of functions and a GUI which can be used to create glyphs from spherical Self-Organizing Feature Maps (SOFMs). It is freely distributable for educational and research purposes.

We have posted a query how to create more number of triangles on sphere like %loads the S-SOFM structure
load c4-24.mat
say C5-48 etc

Is it possible to help us
