Intelligent Data Engineering Group

The Intelligent Data Engineering Group consists of researchers in the Laboratory of Computer and Information Science (CIS) at the Helsinki University of Technology (HUT). The group is headed by professor Olli Simula.


To participate in developing and applying the machine learning, data mining, and visualization methods studied in CIS, and especially, delivering knowledge and know-how of these methods to our industrial partners.

Developing Data Mining, Data Exploration and Information Visualization methods for solving problems in

  • monitoring and controlling industrial processes,
  • telecommunications systems,
  • ecology, and
  • economy.

In these fields, the group has strong contributions to methods based on Self-Organizing Map (SOM). Some present and former members of the group have developed the SOM Toolbox software.
