CLUTO - Software for Clustering High-Dimensional Datasets

The CLUTO data clustering package is currently distributed as a single file that contains binary distributions for Linux, Sun, OSX, and MS Windows platforms.

Getting the files
The first step in getting and using CLUTO is to download the binary distribution file. CLUTO's distribution is available as either a Unix gziped tar file or as a Windows zip file.
Available files for download
Latest experimental release (2.1.2a):
cluto-2.1.2a.tar.gz (20MB) Linux (i686/x86_64), OSX (ppc/i386), SunOS, MSWin (x86_32, x86_64) (20MB) Linux (i686/X86_64), OSX (ppc/i386), SunOS, MSWin (x86_32, x86_64)
Latest stable release (2.1.1):
cluto-2.1.1.tar.gz (9.3MB) Linux i686, SunOS, MSWin (9.3MB) Linux i686, SunOS, MSWin

Older versions of CLUTO can be found here.

On Unix systems, after downloading CLUTO you need to uncompress and untar it. This is achieved by executing the following command:
gunzip cluto-xxx.tar.gz

tar -xvf cluto-xxx.tar

Of course, 'xxx' is CLUTO's release number that you have downloaded. On Windows systems, you need to have a zip/unzip program (e.g., winzip) in order to unzip the files. In general, you just need to double click on "" and the file will be unzipped automatically.

At this point you should have a directory named cluto-xxx. This directory contains CLUTO's library, stand-alone clustering programs, and some test datasets.

Instructions describing how to use CLUTO can be found at cluto-xxx/manual.pdf. You can get a PDF copy from here.
Converting Documents into CLUTO's Format
A simple perl script called doc2mat that convertes a set of documents into the vector-space format used by CLUTO is provided by downloading the following tar file: doc2mat-1.0.tar.gz.

You can read its online documentation from here.

The various datasets used in evaluating the performance of CLUTO's clustering algorithms are available by downloading datasets.tar.gz (28MB file).

Finally, the various datasets used in evaluating the Chameleon clustering algorithm are available by downloading chameleon-data.tar.gz.
