VisiRex Overview

VisiRex has been designed to be very easy to use. Users should take a few minutes to read this overview, so they will quickly understand how the program is structured.

Main Program - "VisiRex.exe"

  • Run VisiRex.exe by clicking the desktop icon, or from your Start_Programs menu.
  • Use the FILE menu to open an existing project or create a new project.
  • The VisiRex installation program has installed eight sample projects with data.

Project File - "MyProject.vrp"

  • All VisiRex project files use the extension .vrp (example: "MyProject.vrp").
  • There is no Save menu for your projects. All of your project settings are saved automatically as you work. These settings can be changed at any time.
  • You may create as many projects as you wish. Several projects may share the same data file.
  • The project file is configured to contain the following information:
    1. The name of the data file and table to be used for this project.
    2. All of the statistics collected during project creation.
    3. Which rows are to be used for training and which for testing.
    4. Which fields are to be used for inputs and what field is the target prediction.
    5. A snapshot of the latest rule extraction.
    6. The latest results on your test data.
    7. All checkmarks you have set.
  • Once a new project file is configured, you can experiment with ! Extract Rules and the various report views.

Data File - "MyData.mdb"

  • One data file can be shared by several projects.
  • VisiRex only reads your data file. Your data is never modified in any way.
  • Data files may have any extension, however they must be in MS-Access (.mdb) format.
  • Data files must contain a primary key field.
  • Data files can be created from ASCII data or CSV spreadsheet files using File_Import.
  • VisiRex has several registration levels which determine the maximum number of data rows you may use. Level 1 is free and offers 250 data rows. Sample data downloaded from the VisiRex website can be used regardless of your registration level.
  • Please contact Cormac Technologies Inc. if you wish to donate sample data to the website.
