utilizing a new feed-back fuzzy neural network for solving a system of fuzzy equations
چکیده
this paper intends to offer a new iterative method based on arti cial neural networks for finding solution of a fuzzy equations system. our proposed fuzzi ed neural network is a ve-layer feedback neural network that corresponding connection weights to output layer are fuzzy numbers. this architecture of arti cial neural networks, can get a real input vector and calculates its corresponding fuzzy output. in order to nd the approximate solution of the fuzzy system that supposedly has a real solution, rst a cost function is de ned for the level sets of the fuzzy network and target output. then a learning algorithm based on the gradient descent method is used to adjust the crisp input signals. the present method is illustrated by several examples with computer simulations.
