| Abstract: | A new methodology of extracting rules from linguistic neural networks is proposed. A linguistic neural unit, which has the ability to analyze continuous input variables in open districts and produces corresponding linguistic variables, is described. The training method for network with linguistic neural layer is discussed. The rules extracted are represented in concise and comprehensible If-Then forms, and don't need to be simplified further. An example showing how to extract rules automatically from the expert domain knowledge for intelligent tutoring system (ITS) is given. |
