Announcing the DOS release of the port of version 2.7 of AutoClass C, 
the Bayesian classifier which seeks a maximum posterior probability 
classification.

Key features:
 - determines the number of classes automatically;
 - can use mixed discrete and real valued data;
 - can handle missing values;
 - processing time is roughly linear in the amount of the data;
 - cases have probabilistic class membership;
 - allows correlation between attributes within a class;
 - generates reports describing the classes found; and 
 - predicts "test" case class memberships from a "training"
   classification.

Inputs consist of a database of attribute vectors (cases), either real
or discrete valued, and a class model.  Default class models are provided.
AutoClass finds the set of classes that is maximally probable with
respect to the data and model.  The output is a set of class descriptions,
and partial membership of the cases in the classes.

Summary of updates:

      Version: 1.0 = 14 Oct 95  Port of AutoClass C to
                      corresponds to AutoClass C UNIX/LINUX/IRIX
        version 2.7.  Note that it is in a separate distribution file:
        AUTOCLAS.ZIP.

-----------------------------------------------------------------------------
The DOS port was done by Juraj Betak (jbetak@rz.fh-augsburg.de).
-----------------------------------------------------------------------------

This DOS port of the UNIX version of AutoClass has been done carefully 
and to the best of my abilities.  There is no warranty though that it 
will perform as well as the original UNIX version.

AUTOCLAS.ZIP was created by the pkzip utility, version 1.1 (03/1990), 
and should be upward compatible to any more recent pkunzip version.  
The executable form of the program (PKUNZIP.EXE) is obtainable from the
FTP site.  To unpack all the files along with the directory hierarchy, 
type:
                      'PKUNZIP -D AUTOCLAS.ZIP' 

For information or help concerning the AutoClass program, see the contact
below.  AutoClass is *not* copyrighted software.

Please check csr.uta.edu:/pub/Readme, whether new version has been released 
in the meantime. There might not exist a complete DOS port of the newest 
version at this time, again please check the WWW site below or the FTP site.

FTP site:   csr.uta.edu:/pub/AUTOCLAS.ZIP   (transfer in binary mode)

Alternate FTP site:
            ftp.gmd.de:/incoming/AUTOCLAS.ZIP   (transfer in binary mode)

When you have trouble in obtaining GNU C via ftp, just turn to the SimTel
site at:       

             ftp.coast.net:/SimTel/vendors/djgpp
       or    http://www.coast.net/SimTel/    (look for vendors collection)

please, look for the basic files needed to run GNU C:

             gcc260dc.zip (Standard docs)
             bnu24bn.zip   	
             djdev112.zip 
             gcc260bn.zip (compiler binaries) 
             djeoe112.zip 
             gas23bn.zip  (assembler) 

The numbers might differ, when a newer version has been released in the
meantime.

GNU C is distributed under the GNU Software licence and is more or less free, 
unless you intend to use it in commercial applications. 

The SimTel collection is one of the largest PC Software sources and it is
also very well maintained. SimTel has lots of mirrors around the worlid, 
there is a good chance that you have one just "next doors" and don't have 
to access a foreign site (in case your ftp access is limited). 
	 
--------------------------------------------------------------------------------

The latest UNIX/IRIX/Linux version of AutoClass is available free of charge, 
and may be obtained via anonymous FTP from the same site.
