Retrieve Experimental Software Version 1 for
Principal Direction Divisive Partitioning

Use this form to retrieve three matlab function files that implement the basic Principal Direction Divisive Partitioning method. This software requires the use of Matlab 5.x or better. This is being posted on the WWW in order to facilitate others experimenting with the method to see if it may meet their needs. However, it is definitely not designed to be a production code in any sense of the word. It has been successful on applications derived from text document clustering, based on a matrix of word counts which must be supplied. This software does only the basic partitioning/clustering of the dataset. Some software to provide a taxonomy or labels for the clusters is included, but this is less developed and less documented than the main clustering software. An experimental update has recently been posted here.

See description on D. L. Boley: Principal Direction Divisive Partioning, TR-97-056, 1997.

Good Luck.
