NNDT
Neural Network Development Tool
Evaluation version 1.2
Bj÷rn Saxen
1995
The NNDT software is as a tool for neural network training. The user
interface is developed with MS Visual Basic 3.0 professional edition.
DLL routines (written in C) are used for most of the mathematics. The
program can be run on a personal computer with MS Windows, version 3.1.
Evaluation version
------------------
This evaluation version of NNDT may be used free of charge for personal
and educational use. The software certainly contains limitations and bugs,
but is still a working version which has been developed for over one year.
Comments, bug reports and suggestions for improvements can be sent to:

Remember, this program comes free but with no guarantee!
A user's guide for NNDT is delivered in PostScript format. The
document is split into three parts and compressed into a file
called MANUAL.ZIP. Due to many bitmap figures included, the total
size of the uncompressed files is very large, approx 1.5M.
Features and methods
--------------------
The network algorithms implemented are of the so called supervised type.
So far, algorithms for multi-layer perceptron (MLP) networks of
feed-forward and recurrent types are included. The MLP networks are
trained with the Levenberg-Marquardt method.
The training requires a set of input signals and corresponding output
signals, stored in a file referred to as pattern file. This is the only
file the user must provide. Optionally, parameters defining the pattern
file columns, network size and network configuration may be stored in a
file referred to as setup file.
NNDT includes a routine for graphical presentation of output signals,
node activations, residuals and weights during run. The interface also
provides facilities for examination of node activations and weights as
well as modification of weights.
A Windows help file is included, help is achieved at any time during
NNDT execution by pressing F1.
Installation
------------
Unzip NNDTxx.ZIP to a separate disk or to a temporary directory e.g.
to c:\tmp. The program is then installed by running SETUP.EXE.
See INSTALL.TXT for more details.
