The atree adaptive logic network (ALN) simulator has an OCR demo (with
C and C++ source code for PCs under Windows 3.x.).  The package is
quite thoroughly documented in an on-line help.

Some people have said they would like to develop full OCR systems
based on the atree demo, but so far, there are no reports of a full
OCR project being completed.  I hope some persons will comment if they
are working on one.

Anyway, here's the info about the package.

Best wishes,

Bill


THE ATREE ADAPTIVE LOGIC NETWORK SIMULATION PACKAGE

The latest release of the atree adaptive logic network (ALN)
simulation package, atree release 2.7, is available via anonymous ftp
from menaik.cs.ualberta.ca [129.128.4.241] in directory pub/ (use
binary mode).  It runs on IBM PCs and compatibles under Windows 3.x.
Included is documentation and ON-LINE HELP that will help you to
understand the basic principles of adaptive logic networks and enable
you to try out some examples of your own creation.  All C and C++
source code is provided.

The atree package is not a toy, despite the fact that it is used for
demonstration purposes, and is non-commercial.  Experimenters are
using it on challenging problems of medicine, physics and the
environment.  It has been used to grade beef based on ultrasound
images, design hardware to discriminate particles produced by an
accelerator, help to design walking prostheses for spinal cord damaged
patients and measure the composition of tarsands from spectral data.

It is possible to use inexpensive, off-the-shelf programmable logic
devices to realize the results of training ALNs in high-speed
hardware, though we do not provide those facilities in the atree
software.

Please read the license, and the warranty (that protects the
developers, not the users).  All neural networks which are "black
boxes" trained and tested on sample data are possibly unsafe, i.e.
unexpected outputs can occur. The current free atree package is no
exception.  A commercial version is planned for later release, and
eventually a safe design methodology will be available.

We shall use release 2.7 as an example here, but please see what the
latest version number is before you ftp the software by examining the
contents of pub/.  Atree release 2.7 is available in either of two
files in this directory: atre27.exe and a27exe.exe.  The file
atre27.exe contains the full C and C++ sources for those who want to
program some applications using Borland C++ 3.x and Application
Frameworks, or some similar C/C++ development environment.  The other,
smaller file contains just the executables for those who just want to
try out atree release 2.7.

Everyone should have a look at the OCR demo!  It has been referred to
as "quite impressive" by experts in the OCR area.  Test yourself
against the trained ALNs, and scribble in your own characters (similar
to the A, L, or N; or pick any language, any alphabet and then train)
to see how noisy and distorted the characters can be, yet still be
recognized by the logic networks.  The demo can be obtained without
the rest in pub/a27ocr.exe.

To set up your software on the PC under Windows 3.x, it is recommended
that you execute atre27.exe in your main directory, whereupon it will
create a subdirectory atree_27 and extract everything into it.
Running "setup" in that directory will create a group of icons you can
use to invoke demos and the facilities for programming adaptive logic
network applications in the lf language.  The "Open" command gives you
access to numerous instructive examples.  Clicking on the Help button
gives you access to explanations of theory and code.

The Unix version, atree release 2.0, will be upgraded sometime to add
some of the functionality of release 2.7.  It is not yet capable of
the nice color displays of the Windows version, but besides running on
Unix workstations it can be easily ported to Macintosh, Amiga, and
other machines.

Thanks to all those who have sent comments about their work on ALNs,
and have helped us to develop new concepts at a rapid rate. We would
appreciate your continued help in finding any problems in the latest
release.

Welcome to the world of adaptive logic networks!
