Abstract: The aim of the present paper is to use the techniques of self-organizing map (SOM) in the process of e-learning to assess the students’ knowledge on relevant topics in intuitionistic fuzzy form. The evaluation is formed on the basis of their answers. The self-organizing map is an effective tool for the visualization of high-dimensional data and its clustering. By clustering, students are classified into “similar” groups according to their intuitionistic fuzzy estimations. Thereby, a three-dimensional map for visualization of their knowledge in the intuitionistic fuzzy form is obtained.
