Remembrance of neural network and neural network or study manner, and uses neural network the fuzzy inference device

摘要

PURPOSE:To obtain the fuzzy inference device which is applicable to the prediction, diagnosis, control, etc., of a process and further stable and highly accurate by providing a fuzzy qualitative evaluating means which evaluates input information qualitatively and supplying =1 qualitative evaluated value to an input layer for each piece of input information. CONSTITUTION:A 1st fuzzy qualitative evaluating means 2 after evaluating the input information qualitatively with a membership function determined by experimental knowledge and normalizing a dynamic range inputs the result to the input layer of the neural network 3. A 2nd fuzzy qualitative evaluating means 4 performs a quantizing process by using the output value of the neural network 3 as the qualitative evaluated value of the experimentally determined membership function. Consequently, even input information having large nonlinearity or much indeterminateness can accurately be evaluated. Further, the information can be normalized to a specific range, so even input information having different property makes learning and remembering stable and highly accurate.
