内容简介:In this talk, two novel approaches termed Dynamic Self-Generated Fuzzy Q-Learning (DSGFQL) and Enhanced Dynamic Self-Generated Fuzzy Q-Learning (EDSGFQL) for automatically generating Fuzzy Inference Systems (FISs) will be presented. In the DSGFQL approach, the structure and preconditioning parts of an FIS are generated by Reinforcement Learning (RL) and the epsilon completeness criterion while the consequents are updated by Fuzzy Q-Learning, which is a widely used RL method. An extended Self Organizing Map (SOM) algorithm is used for adjusting the centers of Membership Functions (MFs) to enhance the proposed DSGFQL. The proposed DSGFQL and EDSGFQL methodologies can automatically create, delete and adjust fuzzy rules dynamically and they are superior to most of the existing RL methodologies in generating FISs. Simulation studies on wall-following and obstacle avoidance tasks by a mobile robot show that the proposed approaches are superior.
