Tasks and Aims

Within the German Society of Computer Science (GI) a research group Fuzzy Systems was founded in October 1993. This group is part of the AI division of the GI. Subjects of the group are the topics Fuzzy Set Theory, Fuzzy Logic, Approximate Reasoning, Fuzzy Control, Uncertainty and Vagueness in Knowledge Based Systems and Fuzzy Data Analysis.

In addition to this, the interest of the group focusses on industrial applications in the field of control engineering (e.g. robotics) as well as speech and pattern recognition. Moreover, neighboring areas like Neural Nets, Machine Learning, and conventional control techniques are considered with respect to fuzzy theory.

By organizing workshops the research group supports

The research group promotes international, especially European cooperations of research in the domain of fuzzy systems.

An important activity of the group is the periodical workshop "Fuzzy Systems" held annually in different places in Germany.

Computational Intelligence '00 - in Baden-Baden

The workshop "Computational Intelligence in Industrial Applications (CI'2000)" was held on 11./12. May in the "Kongresshaus Baden-Baden". Under the organization of Prof. Dr. Sigrid Hafner (Universität Paderborn), Prof. Dr. Harro Kiendl (Universität Dortmund), Prof. Dr. Rudolf Kruse (Universität Magdeburg), and Hans-Paul Schwefel (Universität Dortmund) current research topics was presented, including Fuzzy Systems, Neural Networks, Evolutionary Algorithms and - of increasing interest in Computational Intelligence - Data Mining. (A German conference report can be found here.)

The workshop proceedings have been published as VDI-Bericht 1526, VDI Verlag Düsseldorf (ISBN 3-18-091526-9).

Fuzzy-Neuro Systems '99

Computational Intelligence - in Leipzig

Fuzzy-Neuro Systems `99 was the sixth event of a well established series of workshops with international participation. It was held in Leipzig, March 18 - 19, 1999. Its aim was to give an overview of the state of the art in research and development of fuzzy systems and artificial neural networks. Another aim was to highlight applications of these methods and to forge innovative links between theory and application by means of creative discussions. FNS'99 was organized by the Research Committee 1.2 "Inference Systems" (Fachausschuss 1.2 "Inferenzsysteme") of the German Society of Computer Science GI (Gesellschaft für Informatik e. V.) and Universität Leipzig.

There were 18 contributions from different research areas in fuzzy-neuro systems, with a stress on fuzzy classification and fuzzy image processing. The invited talks were given by P. Hájek on fuzzy predicate calculus, R. Rojas on neural networks for recognition of handwritten ZIP codes, and S. Thrun on algorithms for mobile robotics.

Workshop Chairs: Gerhard Brewka and Siegfried Gottwald.
Local Organization: Ralf Der and Andreas Schierwagen.

The proceedings are available as
Fuzzy-Neuro-Systems'99 - Computational Intelligence - FNS'99.

Fuzzy-Neuro Systems '98

Computational Intelligence - in Munich

The 5. International GI-Workshop Fuzzy-Neuro Systems 98 - Computational Intelligence was held from March 18 - 20, 1998 in Munich at the European Patent Office. The chairman was Prof. Dr. W. Brauer, Technical University of Munich.

Fuzzy-Neuro Systems '97

Computational Intelligence - in Paderborn

Fuzzy-Neuro Systems'97 - Computational Intelligence (see also the Homepage) was the fourth workshop of a series of national meetings in the area of fuzzy systems and artificial neural networks. The workshop was held on March, 12 to 14, 1997 at the University of Paderborn. The emphasis was given to Computational Intelligence. The Chairman was A. Grauel. Invited speakers were J. Bezdek, E.-P. Klement, T. Kohonen and P. Schwefel
