About the Software

The simple and intuitive software has been created by Igor Grešovnik and Tadej Kodelja. It is aimed at exploring properties and function of modelling by artificial neural networks. The software is based on the Investigative Generic Library (IGLib) and uses the Aforge.Net neural network library. See the User Manual and the Documentation Section for more details.

Documentation

NeurApp User Manual. PDF document containing instructions for installation, running, and using the software, and some background information about the software. Also available as html page and mhtml document.

NeurApp License Agreement. Contains terms of use of the software.

ReadMe file. Contains very basic information about the software.

NeurApp Code Documentation (base index). Code documentation for the software, automatically generated from documentation comments by Doxygen. Only the top-level part of code and the most relevant libraries are documented here. For additional documentation of base libraries, see the IGLib Code documentation.

Free Download

NeurApp can be downloaded here and can be used free of charge by anyone (see the license agreement). The current version is 1.0.

Download NeurApp (click on the link) or 32-bit version for older (32 bit) Windows systems.

Short installation instructions:

Download the compressed archive by clicking on the download link above.
Unpack contents of the archive to an arbitrary directory.
Run the executable from the location where files were unpacked.
That's it. For more information about how to use the application, run it, click on the "About" tab and then on the "Help" button, or read the user manual.

System Requirements

The application requires the 64 bit .NET framework or its alternative implementation such as Mono. One of these is available for most modern computing platforms and are many times pre-installed with the operating system. If not yet installed, you will have to download and install the .NET framework (for Widows operating systems) or Mono (cross platform) before using the software.
There may be problems with using the software on some older platforms, e.g. Windows XP. For more details, see the System Requirements Section at the IGLib pages.
