Description
            Clustering Toolbox version 3.1
Copyright (c) by Dr. Eng. (J) Harald Galda, 2011

This toolbox implements functions for clustering and for evaluating clustering
algorithms.

The following functionality is provided:

1.  Random selection of row vectors from a matrix

2. Crisp clustering
- calculation of distances between sample vectors and cluster centers
- nearest neighbor search
- quantization error calculation
- c-means clustering
- Davies-Bouldin index

3. Fuzzy clustering
- fuzzy membership calculation
- fuzzy quantization error calculation
- fuzzy c-means clustering
- Xie-Beni index

4. Self organizing maps
- intialization with regular grid
- training
- mapping sample vectors to places on self organizing map

5. Visualization
- scatter plot of 2D principal component analysis

The data in the file IrisData.csv have been taken from the URL

Changes between versions 3.1 and 3.0
- error in GetXieBeniIndex corrected

Hi,

This seems to be a very well designed module.

Here is the list of functions:
 * CMeans — performs c-means clustering
 * CreateDistanceMatrix — calculates the distances between vectors.
 * FuzzyCMeans — performs fuzzy c-means clustering.
 * FuzzyQuantizationError — calculates the fuzzy quantization error.
 * GetDaviesBouldinIndex — calculates the Davies-Bouldin index.
 * GetFuzzyMemberships — calculates the membership values of vectors in fuzzy clusters.
 * GetNearestNeighbor — calculates for each sample vector the nearest neighbor among a
set 
of cluster centers.
 * GetPlaceOnSOM — maps sample vectors to places on self organizing map.
 * GetQuantizationError — calculates the sum of distances between sample vectors and 
cluster centers.
 * GetXieBeniIndex — calculates the Xie-Beni index.
 * InitSOM — initializes the weight vectors of a self organizing map (SOM) with a regular

grid.
 * PCAScatterPlot — performs a 2D principal component analysis (PCA) and visualizes it.
 * SelectRandomly — selects a specified number of vectors from a set randomly.
 * TrainSOM — trains a self organizing map (SOM).

The functions are well documented and provided in 3 languages: US, DE, JP.
Examples are provided and all of them work perfectly. 
There are 3 demos:
 * c-means
 * fuzzy c-means
 * self organizing map
and they work very well. 
Thank you for providing such a great module !

But I do not understand why it is not packaged under ATOMS ?

Regards,

Michaël Baudin

The toolbox is package under ATOMS. However, the 64 bit Windows package created by ATOMS 
compilation chain does not contain online help. Therefore, this package is disabled and 
replaced by a simple file that can be loaded on 64 bit Windows and does contain online 
help.

The package for 32 bit Windows works perfectly on the 64 bit Windows version of Scilab-
5.3.3.

I installed the Toolbox on MAC OSX 64 bits from ATOMS. However, when I start the Scilab
application, the console 
returns this error message. I would like some light on it. What does it mean and how can I
fix it?


Startup execution:
  loading initial environment

 
 CLUSTER - Clustering Toolbox 3.1   

Start Fuzzy Toolbox 0.4.2
	Load macros
atomsLoad: An error occurred while loading 'sciFLT-0.4.2-2':
	Undefined variable: TCL_SetVar


Thanks and regards, 

Dolores Sanchez
