ViDaExpert 1.0

 

Tool For Multidimensional Data Visualization

(Implementation of the Method of Elastic Maps)

 

 

 

ViDaExpert 1.0 is unique software tool for visualization of multidimensional datasets.

It allows to make understandable color illustrations of a dataset to explore its intrinsic patterns and regularities.

The main technique implemented in ViDaExpert is the Method of Elastic Maps advanced analogue of the Method of Self-Organizing Maps. Besides, there are many other methods of data analysis, including Principal Components Analysis, different clustering methods, Linear Discriminate Analysis, Linear Regression Method. The main principle of the program is to make every step of data analysis clear, understandable and visually represented.

The program was used successfully in several projects concerning data analysis. You can learn much more about this from the following links:

 

* GORBAN Alexander N., ZINOVYEV Andrey Yu. :  Visualization of Data by Method of Elastic Maps and Its Applications in Genomics, Economics and Sociology (PS, PDF)

* ZINOVYEV Andrey Yu. : Visualization of Multidimensional Data (in Russian) ( HTML ).

 

You can download current version of ViDaExpert here. It will work under Windows'95'98'NT4'2000. The program is free for non-commercial use.

You can learn more about using ViDaExpert from the following presentations:

 

* VIDAEXPERT OVERVIEW ( PDF)

* VIDAEXPERT: CREATING DATASET ( PDF)

* VIDAEXPERT: DATASET VISUALIZATION ( PDF)

* VIDAEXPERT: DATA ANALYSIS ( PDF)

 

Here you can download packet with examples of datatable, dataset and map files for Iris database.

To work with standard data tables in dBase (*.dbf) and Paradox (*.db) formats, you will need to install Borland DataBase Engine version 5.0 or later.
