Arbeitsgebiete

The key part of my research work is covered by approximate reasoning with fuzzy systems. The investigations are based on the fact that humans are able to make reasonable decisions though their domain knowledge is often only vague or uncertain. The aim of my work is to find a flexible representation of vague and/or uncertain knowledge and an efficient way to reason on the basis of the knowledge. I especially focus on rule based systems.

The approximate reasoning techniques are applied in the DFG-project Fynesse (FuzzY-NEuro-SyStEm) that deals with autonomous learning of strategies for optimal sequential decisions in large domains. The important questions for the fuzzy part are

  1. the integration of imperfect prior knowledge about the strategy into a reinforcement learning approach,
  2. the interpretation of a learned strategy in terms of fuzzy rules (rule extraction).
