An Efficient Algorithm of Polygonal Fuzzy Neural Network
نویسنده
چکیده
Symmetric polygonal fuzzy number is employed to build an improved feedforward fuzzy neural network (FNN). First, a novel fuzzy arithmetic and extension principle for the polygonal fuzzy numbers is derived. Second, the topological architecture of a three layer feedforward FNN is presented, and the input-output law of this network is systematically studied. Third, a fuzzy BP learning algorithm for the polygonal fuzzy number connection weights and thresholds of the FNN is developed. Finally a simulation example is illustrated to analyze the adaptive three layer feedforward FNN to realize data pairs consisting of real numbers and symmetric polygonal fuzzy numbers, approximately. Keywards: n-polygonal fuzzy number; Fuzzy arithmetic; Feedforward fuzzy neural network; Fuzzy BP algorithm
