- Some time ago we released the software package "LVQ_PAK" for
- the easy application of Learning Vector Quantization algorithms.
- Corresponding public-domain programs for the Self-Organizing Map (SOM)
- algorithms are now available via anonymous FTP on the Internet.
-
- "What does the Self-Organizing Map mean?", you may ask --- See the
- following reference, then: Teuvo Kohonen. The self-organizing map.
- Proceedings of the IEEE, 78(9):1464-1480, 1990.
-
- In short, Self-Organizing Map (SOM) defines a 'non-linear projection'
- of the probability density function of the high-dimensional input data
- onto the two-dimensional display. SOM places a number of reference
- vectors into an input data space to approximate to its data set in an
- ordered fashion.
-
- This package contains all the programs necessary for the application
- of Self-Organizing Map algorithms in an arbitrary complex data
- visualization task.
-
- This code is distributed without charge on an "as is" basis.
- There is no warranty of any kind by the authors or by Helsinki
- University of Technology.
-
- In the implementation of the SOM programs we have tried to use as
- simple code as possible. Therefore the programs are supposed to
- compile in various machines without any specific modifications made on
- the code. All programs have been written in ANSI C. The programs are
- available in two archive formats, one for the UNIX-environment, the
- other for MS-DOS. Both archives contain exactly the same files.
-
- These files can be accessed via FTP as follows:
-
- 1. Create an FTP connection from wherever you are to machine
- "cochlea.hut.fi". The internet address of this machine is
- 130.233.168.48, for those who need it.
-
- 2. Log in as user "anonymous" with your own e-mail address as password.
-
- 3. Change remote directory to "/pub/som_pak".
-
- 4. At this point FTP should be able to get a listing of files in this
- directory with DIR and fetch the ones you want with GET. (The exact
- FTP commands you use depend on your local FTP program.) Remember
- to use the binary transfer mode for compressed files.
-
- The som_pak program package includes the following files:
-
- - Documentation:
- README short description of the package
- and installation instructions
- som_doc.ps documentation in (c) PostScript format
- som_doc.ps.Z same as above but compressed
- som_doc.txt documentation in ASCII format
-
- - Source file archives (which contain the documentation, too):
- som_p1r0.exe Self-extracting MS-DOS archive file
- som_pak-1.0.tar UNIX tape archive file
- som_pak-1.0.tar.Z same as above but compressed
-
-
- An example of FTP access is given below
-
- unix> ftp cochlea.hut.fi (or 130.233.168.48)
- Name: anonymous
- Password: <your email address>
- ftp> cd /pub/som_pak
- ftp> binary
- ftp> get som_pak-1.0.tar.Z
- ftp> quit
- unix> uncompress som_pak-1.0.tar.Z
- unix> tar xvfo som_pak-1.0.tar
-
- See file README for further installation instructions.
-
- All comments concerning this package should be
- addressed to som@cochlea.hut.fi.
