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 it’s 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:
